+
+ Accommodate C++11 string constant conflation limitations.
+
+ * src/dllhook.cpp (MSG_INTERNAL_ERROR)
+ * src/pkgexec.cpp (LUA_LIBEXEC_PATH): Insert white space, to separate
+ adjacent string constants in conflated text.

+
+ Force "C" linkage for setup key definitions.
+
+ * src/setup.cpp (uri_key, mirror_key, value_none): Wrap them...
+ (BEGIN_C_DECLS, END_C_DECLS): ...between these.
+
+2020-06-19 Keith Marshall <keith@users.osdn.me>
+
+ Support all-static linking with recent GCC versions.
+
+ * Makefile.in (LDFLAGS): Add "-static" unconditionally.
+ (LIBS, SETUP_TOOL_LIBS): Remove all "-Wl,-Bstatic" and "-Wl,-Bdynamic"
+ references; the latter, in particular, appears to induce dynamic
+ linking of libstdc++-6.dll, overriding "--static-libstdc++".

+
+ Use XML templates to adapt to download host changes.
+
+ * configure.ac (MINGW_PACKAGE_DIST_URL): Update to OSDN host URL.
+
+ * xml/profile.xml: Rename it as...
+ * xml/profile.xml.in: ...this; replace hard-coded repository URL...
+ (%PACKAGE_LIST_URL%/%F.xml.lzma): ...this template.
+
+ * xml/setup.xml: Likewise, rename it as...
+ * xml/setup.xml.in: ...this, with corresponding URL update.
+
+ * Makefile.in (install-profile): Modify procedure, using...
+ (%.xml: %.xml.in): ...this new pattern rule, to generate installed XML
+ files, from source templates.
+
+ * src/setup.rc (STRINGTABLE) <ID_DOWNLOAD_HOST_URI>: Remove trailing
+ "?download" qualifier.
+

+
+ Discontinue formal use of the build-aux submodule.
+
+ * .gitmodules .hgsub: Files are obsolete; delete them.
+ * .gitignore .hgignore (build-aux): Add to SCM exclusion list.
+
+ * aclocal.m4 (build_aux_prefix): New macro; define it. This provides
+ a mechanism for informally locating an external, separately maintained
+ implementation of the requisite "build-aux" module; use it in...
+ (aux_include): ...this new macro; define, and use it, to access those
+ "build-aux" M4 macros which are required at configure generation time.
+ (MINGW_AC_CONFIG_AUX_DIR, MINGW_AC_CONFIG_AUX_DIRS): New macros;
+ define them. Together, they implement a replacement for the standard
+ AC_CONFIG_AUX_DIR macro, but offering extended path search capability,
+ at configure run time, in addition to defining...
+ (buildauxdir): ...this new AC_SUBST variable.
+
+ * configure.ac (build_alias): Define it using...
+ (ac_aux_dir): ...this autoconf path reference, defined by using...
+ (MINGW_AC_CONFIG_AUX_DIR): ...this, instead of...
+ (AC_CONFIG_AUX_DIR): ...this.
+
+ * Makefile.in (buildauxdir): Use it, for M4 file references.
