glibc/posix/fnmatch.c
Roland McGrath 4f54cdb1dd * sysdeps/sparc/elf/start.S: New file.
* sysdeps/sparc/dl-machine.h: New file.

	* posix/fnmatch.c (fnmatch): Fix \*[*?]+ case to increment name ptr
 	only for ?s, not for *s.  Fix from Chet Ramey.

	Fixes thanks to Raja R Harinath <harinath@cs.umn.edu>:
	* sysdeps/unix/sysv/utmpbits.h: Define _HAVE_UT_{TYPE,ID,TV,HOST}.
	Use __{BEGIN,END}_DECLS.
	(_PATH_WTMP, _PATH_UTMP, _PATH_LASTLOG): New macros.
	* login/utmp.h (UTMP_FILE, UTMP_FILENAME, WTMP_FILE, WTMP_FILENAME):
	New macros, moved here from sysdeps/gnu/utmpbits.h.
	* sysdeps/generic/utmpbits.h (_HAVE_UT_HOST): Define it.
	* sysdeps/gnu/utmpbits.h (_HAVE_UT_HOST): Likewise.
	* login/logout.c: Use ut_host only #if _HAVE_UT_HOST.
	Use sizeof instead of UT_*SIZE.
	* login/logwtmp.c: Likewise.

	* misc/tsearch.c (tdelete): Define as weak alias to __tdelete.

	* version.c (banner): Add trailing newline.
