Tue May 19 12:50:27 1998 Craig Burley <burley@gnu.org> Break up main() into separate .o's so making and linking against shared libraries with non-Fortran main() routines is easier: * Makefile.in (MISC): Add setarg.o and setsig.o. * libF77/Makefile.in (MISC): Ditto. * libF77/setarg.c: New file, contains f_setarg(). * libF77/setsig.c: New file, contains f_setsig(). * libF77/getarg_.c: Rename xarg* to f__xarg*. * libF77/iargc_.c: Ditto From-SVN: r19956
