While building X11 with gcc (1.36) and includes fixed, in particular the
file oscolor.c under os/4.2bsd, the cpp could not resolve `fetch' macro
fixed in dbm.h by fixincludes.  Here is some details:

Hardware: sun 3/60,
Software: SunOS 4.0.3, gcc(1.36)
Details:
/*** file tonto.c ***/
#include <dbm.h>

        f= fetch(f);
}
