These are the patches for the gprof subdirectory.

1999-07-30  Eli Zaretskii  <eliz AT is DOT elta DOT co DOT il>

	* gmon_io.h (SET_BINARY) [O_BINARY]: Define.

	* gmon_io.c (gmon_out_read) [SET_BINARY]: Switch stdin into binary
	mode.

	* source.c: Include filenames.h and sys/stat.h.
	(source_file_lookup_path, source_file_lookup_name): Use
	FILENAME_CMP to compare file names.
	(annotate_source) [__MSDOS__]: If "filename-ann" would overwrite
	"filename", replace the extension with ".ann".
	[DOSISH_FILENAMES]: Support file names with backslashes and drive
	letters.
	Use IS_ABSOLUTE.

1999-07-27  Eli Zaretskii  <eliz AT is DOT elta DOT co DOT il>

	* search_list.h (PATH_SEP_CHAR): Define.

	* search_list.c (search_list_append): Use PATH_SEP_CHAR.

	* hertz.c (HERTZ) [__MSDOS__]: Don't define unless they have
	neither HAVE_SETITIMER nor HAVE_SYSCONF.
	[HAVE_SETITIMER]: If they define both HAVE_SETITIMER and
	HAVE_SYSCONF, try setitimer and fall back on sysconf.
