* i386/cygmon.ld: Add entry for .gcc_except_table.
2000-10-25 Mark Salter <msalter@redhat.com>
* i386/cygmon-crt0.S: Use __USER_LABEL_PREFIX__ for symbols. Always
use __start for start symbol.
* i386/cygmon-salib.c: Don't build __do_global_[cd]tors for AOUT.
Disable file I/O extensions to make Plum Hall happy.
* i386/cygmon.ld: Set __start as entry point.
* i386/Makefile.in: Support IS_AOUT.
* i386/configure.in: Support IS_AOUT.
* i386/configure: Regenerated.
* i386/cygmon-salib.c:
* i386/cygmon-gmon.c (_mcount): It's _etext.
