5460 autoconf. If HAVE_UNISTD_H is defined, include unistd.h to get
5461 appropriate definitions of read, write, etc. Add prototype for
5462 system.
5463
5464Tue Feb 4 13:24:44 1997 Doug Evans <dje@canuck.cygnus.com>
5465
5466 * Makefile.in (libcommon.a): Delete.
5467 (callback.o,targ-map.o): Delete, moved to Make-common.in.
5468 (gentmap,targ-vals.h,targ-map.c): Likewise.

5484 comments and single quotes. Fixes a problem found on hpux.
5485

5493 the way that callback.o, gentmap, targ-vals.h, targ-map.c,
5494 targ-map.o, and run are built. They are now built in the
5495 individual simulator directories, taking sources from ../common as
5496 necessary. This replaces the merging of libcommon.a into
5497 linsim.a, which was problematic for the WinGDB build process.
5498 * run.c: Include config.h from . instead of ../common.
5499 * Make-common.in: Remove. It's no longer necessary.

5571
5572 * run.c (main): Removed SH specific comments, so source is
