4269
4270 * aclocal.m4 (COMMON_MAKEFILE_FRAG): Quote a couple of $'s in
4271 comments and single quotes. Fixes a problem found on hpux.
4272
4273Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
4274
4275 * aclocal.m4: Remove Make-common.in from dependencies.
4276 * (distclean): Remove targ-vals.def.
4277
4278 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
4279 into here. Makes insertion into makefiles easier. Also, change
4280 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
4281 targ-map.o, and run are built. They are now built in the
4282 individual simulator directories, taking sources from ../common as
4283 necessary. This replaces the merging of libcommon.a into
4284 linsim.a, which was problematic for the WinGDB build process.
4285 * run.c: Include config.h from . instead of ../common.
4286 * Make-common.in: Remove. It's no longer necessary.

4358
4359 * run.c (main): Removed SH specific comments, so source is
