5453 comments and single quotes. Fixes a problem found on hpux.

5455Thu Jan 23 13:35:03 1997 Stu Grossman (grossman@critters.cygnus.com)
5456
5457 * aclocal.m4: Remove Make-common.in from dependencies.
5458 * (distclean): Remove targ-vals.def.
5459
5460 * aclocal.m4 (SIM_AC_COMMON): Move contents of Make-common.in
5461 into here. Makes insertion into makefiles easier. Also, change
5462 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5463 targ-map.o, and run are built. They are now built in the
5464 individual simulator directories, taking sources from ../common as
5465 necessary. This replaces the merging of libcommon.a into
5466 linsim.a, which was problematic for the WinGDB build process.
5467 * run.c: Include config.h from . instead of ../common.
5468 * Make-common.in: Remove. It's no longer necessary.

5540
5541 * run.c (main): Removed SH specific comments, so source is
