* csu/Makefile (crtstuff): New variable consolidates crti, crtn; add crti_s, crtn_s. (install-lib, extra-objs, generated-, omit-deps): Use that. (initfini): New canned sequence, broken out of crt[in].s rule. (crt[in].s rule): Use it. (crt[in]_s.s): New rule. * csu/initfini.c (GLOBAL): New macro; define it to empty if undefined. (_init, _fini): Use GLOBAL as storage class. Add self reference to avoid GCC optimizing out the functions. * Makefile (headers): Remove $(stddef.h). * Makeconfig (stddef.h): Variable removed; now require gcc version >= 2.2. * stddef.h: File removed. Mon Feb 20 19:42:31 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu> * sysdeps/unix/bsd/ultrix4/mips/start.S: Remove `__environ' definition. * sysdeps/unix/bsd/osf1/alpha/start.S: Likewise. * stdlib/strtod.c: Allow the string to start with a decimal point without a leading zero.
