* 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.
