4665
4666Fri Jan 31 07:16:49 1997 Doug Evans <dje@canuck.cygnus.com>
4667

4672
4673 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
4674 comments and single quotes. Fixes a problem found on hpux.
4675
4676Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
4677
4678 * aclocal.m4: Remove Make-common.in from dependencies.
4679 * (distclean): Remove targ-vals.def.
4680
4681 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
4682 into here. Makes insertion into makefiles easier. Also, change
4683 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4684 targ-map.o, and run are built. They are now built in the
4685 individual simulator directories, taking sources from ../common as
4686 necessary. This replaces the merging of libcommon.a into
4687 linsim.a, which was problematic for the WinGDB build process.
4688 * run.c: Include config.h from . instead of ../common.
4689 * Make-common.in: Remove. It's no longer necessary.

4729
4730 * run.c: Include stdarg.h if __STDC__.
4731
4732Tue Oct 15 11:16:31 1996 Jeffrey A Law (law@cygnus.com)
4733
4734 * run.c (main): Don't print out anything if the signal
4735 number is zero (ie no signal).

4761
4762 * run.c (main): Removed SH specific comments, so source is
