+ * cygheap_malloc.h: New file.
+ * cygheap.h: Remove stuff now included in cygheap_malloc.h and include
+ that file. Make cygheap_init a standard c++ function. Remove unneeded
+ child_info declaration.
+ * path.h: Include cygheap_malloc.h. Remove extra cstrdup declaration.
+ (path_conv): Reorganize to group variables together.
+ (path_conv::path): Make const char *.
+ (path_conv::known_suffix): Ditto.
+ (path_conv::normalized_path): Ditto.
+ (path_conv::path_conv): Reorganize initializers to reflect new element
+ ordering.
+ (path_conv::get_win32): Change return value to const char *.
+ (path_conv::set_path): Move back here from spawn.cc.
+ (parh_conv::modifiable_path): New function.
+ * path.cc (path_conv::add_ext_from_sym): Accommodate const'ness of
+ known_suffixes.
+ (path_conv::set_normalized_path): Ditto for normalized_path.
+ (path_conv::check): Use modifiable_path whereever we need to modify the
+ path element. Use set_path to set the path.
+ (path_conv::~path_conv): Accommodate new const'ness.
+ * spawn.cc (perhaps_suffix): Declare ext as const since that's what is
+ being returned.
+ (path_conv::set_path): Move back to path.h.
+ * winf.f (linebuf): Perform minor cleanup.
+ (linebuf::fromargv): Change second parameter to const.
+ * winf.cc (linebuf::fromargv): Ditto.
+
+2009-08-01 Christopher Faylor <me+cygwin@cgf.cx>
+
* path.h (path_conv::set_path): Change return value.
* spawn.cc (path_conv::set_path): Return newly set value.
(find_exec): Set retval to newly set value when calling set_path.
