More system.h cutover patches:

        * c-parse.in: Include system.h, and remove stuff now made redundant.
        * cccp.c: Likewise.
        * cexp.y: Likewise.
        * protoize.c: Likewise.  Properly check for cpp stringification.
        * Makefile.in (c-parse.o, cccp.o, cexp.o, protoize.o, unprotoize.o):
        Depend on system.h.
        * objc/Make-lang.in (objc-parse.o): Likewise.
