2213 (common makefile fragment): Moved back into ...
2214 * Make-common.in: Resurrect.

2218 Fri Jan 31 07:16:49 1997 Doug Evans <dje@canuck.cygnus.com>
2219

2223 Fri Jan 24 10:37:17 1997 Stu Grossman (grossman@critters.cygnus.com)
2224
2225 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
2226 comments and single quotes. Fixes a problem found on hpux.
2227
2228 Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
2229
2230 * aclocal.m4: Remove Make-common.in from dependencies.
2231 * (distclean): Remove targ-vals.def.
2232
2233 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
2234 into here. Makes insertion into makefiles easier. Also, change
2235 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
2236 targ-map.o, and run are built. They are now built in the
2237 individual simulator directories, taking sources from ../common as
2238 necessary. This replaces the merging of libcommon.a into
2239 linsim.a, which was problematic for the WinGDB build process.
2240 * run.c: Include config.h from . instead of ../common.
2241 * Make-common.in: Remove. It's no longer necessary.

2282 * run.c: Include stdarg.h if __STDC__.
2283
2284 Tue Oct 15 11:16:31 1996 Jeffrey A Law (law@cygnus.com)
2285
2286 * run.c (main): Don't print out anything if the signal

2313
2314 * run.c (main): Removed SH specific comments, so source is
