runtime/mercury_getopt.c:
runtime/mercury_getopt1.c:
Add the files as produced by process_getopt.
runtime/process_getopt:
runtime/mercury_getopt.h:
Avoid a warning if the environment already defines __GNU_LIBRARY__,
and prevent this from omitting the entire bodies of the source files
:-(.
util/getopt.h:
A copy of the old mercury_getopt.h for mkinit.c
util/mkinit.c:
Include getopt.h instead of mercury_getopt.h, since we want getopt(),
not MR_getopt().
