glibc/sysdeps/alpha/elf/configure.in
Ulrich Drepper dd4f211573 Update.
2002-08-28  Jakub Jelinek  <jakub@redhat.com>

	* sysdeps/ia64/elf/configure.in (PI_STATIC_AND_HIDDEN): Define
	unconditionally.
	* sysdeps/alpha/elf/configure.in (libc_cv_alpha_hidden_gprel): New
	check.
	(PI_STATIC_AND_HIDDEN): Define if check succeeded.

2002-08-28  Jakub Jelinek  <jakub@redhat.com>

	* locale/loadarchive.c (_nl_load_locale_from_archive): Add fd >= 0
	check to close_and_out close.  Replace return NULL statements where
	fd might be >= 0 with goto close_and_out.  Close the file descriptor
	when it is no longer needed.
