FWIW, in current sources <stdarg.h> is included *unconditionally* by
c.h, so your problem should go away in 7.1. (This may mean that any
remaining not-quite-ANSI platforms will crash and burn ...) In the
meantime you might check how things work for you if you change c.h to
include <stdarg.h> unconditionally.

Evidently not, else your hand addition of <varargs.h> wouldn't have
changed anything since it'd already have been included. I'm guessing
that your compiler predefines __SVR4.
