Update.

* gnulib/Makefile (tests): Add tst-gcc.
	* gnulib/tst-gcc.c: New file.

	* assert/Makefile (routines): Add __assert.
	* assert/Versions: Export __assert for glibc 2.2.
	* assert/__assert.c: New file.
	* assert/assert.h: Declare __assert.

2000-07-27  Bruno Haible  <haible@clisp.cons.org>

	* locale/localeinfo.h (_ISCTYPE): New macro.
	* posix/fnmatch_loop.c (internal_fnmatch): Use it, support new
	LC_CTYPE locale format.
	* locale/programs/ld-ctype.c (locale_ctype_t): New field class_b.
	(ctype_output): Output class_b[nr] right before class_3level[nr].
	(allocate_arrays): Fill class_b, similarly to class_3level.
