4663Fri Jan 24 10:37:17 1997 Stu Grossman (grossman@critters.cygnus.com)
4664
4665 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
4666 comments and single quotes. Fixes a problem found on hpux.
4667
4668Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
4669
4670 * aclocal.m4: Remove Make-common.in from dependencies.
4671 * (distclean): Remove targ-vals.def.
4672
4673 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
4674 into here. Makes insertion into makefiles easier. Also, change
4675 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4676 targ-map.o, and run are built. They are now built in the
4677 individual simulator directories, taking sources from ../common as
4678 necessary. This replaces the merging of libcommon.a into
4679 linsim.a, which was problematic for the WinGDB build process.
4680 * run.c: Include config.h from . instead of ../common.
4681 * Make-common.in: Remove. It's no longer necessary.

4721
4722 * run.c: Include stdarg.h if __STDC__.
4723
4724Tue Oct 15 11:16:31 1996 Jeffrey A Law (law@cygnus.com)
4725
4726 * run.c (main): Don't print out anything if the signal
4727 number is zero (ie no signal).

4753
4754 * run.c (main): Removed SH specific comments, so source is
