gcc.c: Get system includes...

        * 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".

        * system.h: Fix return type of bcmp prototype from `void' to `int'.
        Make bcopy, bcmp and bzero prototypes explicitly `extern'.
        Add a prototype for getenv.
