Wed Aug 27 09:51:42 1997 Andrew Cagney <cagney@b1.cygnus.com>
* sim-utils.c (sim_copy_argv): Rewrite to match malloc strategy
used by copyargv and freeargv.
* sim-options.c (sim_parse_args): Save a copy of PROG-ARGS in
STATE_PROG_ARGV, not just a pointer.
Mon Aug 25 17:50:22 1997 Andrew Cagney <cagney@b1.cygnus.com>
* configure: Regenerated to track ../common/aclocal.m4 changes.
