egcs, patch for gcc.c to utilize system.h

[Kaveh R. Ghazi]

	This patch makes gcc/gcc.c use system.h.  It requires the patch
to system.h I sent in a previous message.

        * gcc.c: Get system includes, prototypes and macros via "system.h"
        instead of doing it manually.  Change all calls of the ctype
        macros to custom versions defined in "system.h".
