Browse Source 
* 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.

	* 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.
