Tue Feb 21 00:10:50 1995 Roland McGrath <roland@churchy.gnu.ai.mit.edu>
* 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.
