Sun Feb 19 17:46:13 1995 Roland McGrath <roland@duality.gnu.ai.mit.edu> 

* posix/Makefile (aux): Add environ.
	* posix/environ.c: New file.
	* sysdeps/unix/sparc/start.c: Remove __environ definition.
	* sysdeps/unix/start.c: Likewise.
	* sysdeps/unix/sysv/irix4/start.c: Likewise.
	* sysdeps/mach/hurd/start.c: Likewise.
	* sysdeps/mach/start.c: Likewise.
	* sysdeps/stub/start.c: Likewise.

	* sysdeps/unix/make_errlist.c: In produced program, test
 	HAVE_WEAK_SYMBOLS instead of HAVE_GNU_LD.
	* sysdeps/unix/sysv/sysv4/dup2.c: Fix #include of renamed file.
  	Remove extra weak alias.

	* sysdeps/unix/sysv/sysv4/sigaltstack.S: Fix unsquashed file name
 	in #include.

	* libc-symbols.h: Put comment around ^L to pacify Solaris as.

	* sysdeps/posix/Makefile (cded-objdir-includes): New variable
 	replaced cded-objdir-CPPFLAGS; transform $(+includes) instead of
 	$(CPPFLAGS).
	(mk-stdiolim): Use it instead.

	* mach/mach_init.c (__vm_page_size): Make it initialized.  It does
 	not work to make a weak alias to a bss symbol.

	* stdio/Makefile (distribute): Remove mpn-copy.mk; add gen-mpn-copy.
	(tests): Add test-fwrite.
	* stdio/test-fwrite.c: New file.

	* stdlib/stdlib.h [__USE_GNU]: Declare strtof, strtold, __strtof,
 	__strtold.

	* Makefile (autoconf-it): New canned sequence.  Do cvs commit if
 	there is a CVS directory.
	(configure, %/configure): Use $(autoconf-it) for cmds.
	* Make-dist: Likewise.
	* Makerules ($(gpl2lgpl)): Likewise.
 	inlines cause trouble for files defining global register variables.
	* stdio/vfprintf.c: Set PREC to zero for %. without following digit.
