+ 2016-07-14 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Prepare and tag all files for release of mingwrt-3.22.
+
+ * configure.ac (AC_INIT): Adjust package version number.
+
+ 2016-07-14 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Preserve kludge to evade GCC build failure on S_ISBLK misuse.
+
+ * include/sys/stat.h (_NO_UNSUPPORTED): New feature test macro; it
+ should be user defined, if desired, before inclusion; leave undefined.
+ [!_S_IFBLK && !_NO_UNSUPPORTED && !_NO_OLDNAMES] (S_ISBLK): Define it,
+ as appropriate for POSIX conforming usage; do not poison it.
+
+ 2016-07-10 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Fix C++ strict type checking inconsistency in <glob.h>
+
+ * include/glob.h (__ERRFUNC_P): New private macro; define it to match
+ the type signature of the error function pointer, to be passed to...
+ (glob): ...this function; use it to correctly represent error function
+ pointer argument in inline implementation.
+
+ 2016-07-09 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Factor out <ctype.h> vs. <wctype.h> duplicate elements.
+
+ * include/ctype.h: Assert copyright; tidy layout.
+ [!_CTYPE_H_]: Do not evaluate; rename macro to be tested, as...
+ [!_CTYPE_H]: ...this preferred multiple inclusion guard macro name.
+ (__CTYPE_H_SOURCED__): New macro; define it, and include <wctype.h>,
+ so requesting partial inclusion, to retrieve definitions for...
+ (_ALPHA, _BLANK, _CONTROL, _DIGIT, _HEX, _LOWER, _PUNCT, _SPACE)
+ (_UPPER, WEOF): ...these macros; hence, do not define them locally.
+ (wint_t, wchar_t, wctype_t): Likewise these type definitions...
+ (iswalnum, iswalpha, iswascii, iswblank, iswcntrl, iswctype)
+ (iswdigit, iswgraph, iswlower, iswprint, iswpunct, iswspace)
+ (iswupper, iswxdigit, towlower, towupper, is_wctype): ...these function
+ prototypes, and corresponding inline alternative implementations.
+ (_BEGIN_C_DECLS, _END_C_DECLS): Use these as appropriate.
+ [__MSVCRT_VERSION__<=__MSVCR70_DLL]: Likewise.
+
+ * include/wctype.h: Assert copyright; tidy layout.
+ [!_WCTYPE_H_]: Do not evaluate; rename macro to be tested, as...
+ [!_WCTYPE_H]: ...this preferred multiple inclusion guard macro name;
+ do not define it when partial inclusion only is selected, by...
+ [__CTYPE_H_SOURCED__]: ...this; thence define only...
+ (_ALPHA, _BLANK, _CONTROL, _DIGIT, _HEX, _LOWER, _PUNCT, _SPACE)
+ (_UPPER): ...these character characterisation macros...
+ (wint_t, wchar_t, wctype_t): ...these type definitions...
+ (iswalnum, iswalpha, iswascii, iswblank, iswcntrl, iswctype)
+ (iswdigit, iswgraph, iswlower, iswprint, iswpunct, iswspace)
+ (iswupper, iswxdigit, towlower, towupper): ...these function
+ prototypes, with corresponding inline alternative implementations...
+ (is_wctype): ...this further prototype, qualified as deprecated...
+ (WEOF): ...and this status reporting macro.
+ (_ctype, _pctype, _pctype_dll, _imp___ctype, _imp___pctype): Delete
+ declarations, and associated definitions; they do not belong here.
+ (isleadbyte): Likewise, this Microsoft specific function prototype...
+ (_LEADBYTE): ...and this associated character classification macro.
+ (_BEGIN_C_DECLS, _END_C_DECLS): Use these as appropriate.
+
+ 2016-07-04 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Do not pass MAKEFLAGS explicitly, when invoking recursive make.
+
+ * Makefile.in (install-strip, uninstall): Delete explicit $(MAKEFLAGS)
+ references from $(MAKE) command lines; make passes them implicitly.
+
+ 2016-07-03 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Rework tsearch and friends; resolve issues [#1512] and [#1576].
+
+ * include/search.h: Assert copyright; tidy layout.
+ (_SEARCH_H_): Rename this multiple inclusion guard macro...
+ (_SEARCH_H): ...to conform to this preferred standard convention.
+ (__search_comparator): New function prototype typedef; it provides a
+ convenient shorthand notation for argument declarations in functions
+ which require a comparator function pointer; use it where appropriate.
+ (tsearch, tfind, tdelete) [__MINGW_ATTRIB_NONNULL]: Apply to arguments
+ #2 and #3; was previously incorrectly applied to arguments #1 and #3.
+ (twalk) [__MINGW_ATTRIB_NONNULL]: Apply to both arguments #1 and #2.
+ [_SEARCH_PRIVATE] (__MINGW_ATTRIB_NONNULL): Suppress its effect, to
+ ensure that GCC does not optimize away checks within implementation.
+ (_BEGIN_C_DECLS, _END_C_DECLS): Use these.
+
+ * mingwex/tdelete.c: Tidy layout.
+ (tdelete): Reimplement it as a thin wrapper around...
+ (__tdelete): ...this; it encapsulates the original implementation as a
+ __CRT_ALIAS (inline) function, to simplify void ** --> node_t ** casts.
+ Remove unnecessary non-null assertions for arguments #1 and #3; prefer
+ to validate arguments #2 and #3 internally, and simply return NULL if
+ necessary; hence, do not include <assert.h>
+
+ * mingwex/tfind.c: Tidy layout.
+ (tfind): Similarly reimplement it as a thin wrapper around...
+ (__tfind): ...this __CRT_ALIAS (inline) encapsulation of the original.
+ Add non-null validation for argument #3; do not include <assert.h>
+
+ * mingwex/tsearch.c: Tidy layout.
+ (tsearch): Once again, reimplement it as a thin wrapper around...
+ (__tsearch): ...this __CRT_ALIAS variant. Add non-null validation for
+ argument #3; do not include <assert.h>
+
+ * mingwex/twalk.c: Tidy layout; do not include <assert.h>
+
+ 2016-06-28 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Rework __try1/__except1 to resolve issue [#1328].
+
+ * include/excpt.h: Assert copyright; tidy layout.
+ (_EXCPT_H_): Multiple inclusion guard macro renamed to...
+ (_EXCPT_H): ...this; update all references as appropriate.
+ (_BEGIN_C_DECLS, _END_C_DECLS): Use these.
+ (__typecast_alloca): New macro; define it, casting return type of...
+ (__builtin_alloca): ...this to a specified data type; use it in...
+ (__try1_setup, __except1_teardown): ...these new macros; define them
+ as parameterized templates, providing both -masm-att and -masm-intel
+ syntax implementations, with host specific word size and register
+ assignment parameter substitutions; use them to redefine...
+ (__try1, __except1): ...each of these, using __builtin_alloca to avoid
+ direct stack pushes when registering exception handlers; assign the
+ template parameters as appropriate to support implementation for...
+ [_WIN64, _WIN32]: ...either of these, as the host requires.
+
+ 2016-06-17 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Merge Cygwin CVS updates to legacy branch.
+
+ * include/stdio.h: Merge 2011-11-30 and 2012-08-02 commits.
+ (getc, getchar, putc, putchar): Declare function prototypes.
+ (fopen64, ftello64): Likewise; change implementation classification
+ from __CRT_INLINE to __CRT_ALIAS, to avoid C++ emitted code bloat.
+ (_lock_file, _unlock_file): Add prototypes; modify merge to...
+ [__MSVCRT_VERSION__>=__MSVCR80_DLL]: ...require this.

+ (_strtoi64, _strtoui64, _wcstoi64, _wcstoui64): Declare prototypes.
+ [__MSVCRT__VERSION__>=__MSVCR80_DLL || _WIN32_WINNT >= _VISTA]
+ (_strtoi64_l, _strtoui64_l, _wcstoi64_l, _wcstoui64_l): Likewise...
+ [!__have_typedef_locale_t] (__need_locale_t): ...and define to get...
+ (locale_t): ...this, by selective inclusion of <locale.h>
+ [__WCHAR_H_SOURCED] (_wcstoi64, _wcstoui64, _wcstoi64_l)
+ (_wcstoui64_l): Make these function prototypes available for selective
+ inclusion by...
+ * include/wchar.h: ...this; merge 2012-08-02 commit.
+ [__MSVCRT__VERSION__>=__MSVCR70_DLL || _WIN32_WINNT >= _WINXP]
+ (_wcstoi64, _wcstoui64): Note availability of function prototypes via
+ selective inclusion of their actual declarations from <stdlib.h>
+ [__MSVCRT__VERSION__>=__MSVCR80_DLL || _WIN32_WINNT >= _VISTA]
+ (_wcstoi64_l, _wcstoui64_l): Likewise.

+ [__STRICT_ANSI__] (PATH_MAX): Suppress definition.
+
+ * include/sys/param.h: Merge 2012-08-02 commit.

+ [PATH_MAX defined] (MAXPATHLEN): Define it as an alias.
+
+ 2016-06-12 Keith Marshall <keithmarshall@users.sourceforge.net>
+
+ Add typedef and access support for opaque locale_t objects.
+
+ * include/locale.h (locale_t, _locale_t): Define opaque types.
+ [__need_locale_t]: Make them selectively accessible; define...
+ (__have_typedef_locale_t): ...this, when they are available.
+ [_LOCALE_H] (_create_locale, _get_current_locale, _free_locale):
+ Declare function prototypes, on direct <locale.h> inclusion only.
+ [_LOCALE_H || _WCHAR_H] (_wcreate_locale): Likewise; this is to be
+ visible on direct inclusion, or when including <wchar.h>
+
+ * include/stdio.h [!(_STDIO_H && _WCHAR_T)]: Correct expression of...
+ [__MSVCR80_DLL || _WIN32_WINNT_VISTA]: ...this subsidiary condition;
+ for all cases when this is true, (including when [_STDIO_H] alone)...
+ [!__have_typedef_locale_t] (__need_locale_t): ...define this, and
+ include <locale.h>, for selective definition of...
+ (locale_t): ...this.
