flex uses mktemp in such a way as to dump core when compiled with pure
strings.  I made some other changes:

Makefile    Uses $(CC) and $(YACC) rather than cc and yacc.
	    It's easier to generate optimized vs. debugging versions from
		the make command line.
	    Uses $(CLIB) to make it easier to use SysV shared libraries.

flex.h	    Made sprintf() SV dependent: SysV sprintf() returns int.
	    Went ahead and added a full prototype, since my include files
		on bigtex already had the prototype and GNU C is unhappy
		without it in flex.

flexmain.c  Changed usage of mktemp(3) call.
