* config/mh-sparc.h: now uses libgcc.a

* ldmain.c: quit using exit
	* *.sc: use *(COMMON) rather than [COMMON]
	* ldlex.l, lexsup.c: much thinking moved from .l and put into .c,
	to allow preprocessing of .l file.
	* Makefile.in: New ldlex.l mangling
	* ldexp.c (fold_binary): perform expressions with % and / in
	integer.
	* ldfile.c (open_a): open archives on VMS in a special way
	* lderror.c: forgot to check in from a long while ago
