re PR target/26792 (need to use autoconf when using newly-added libgcc functions)
2006-09-26 Jack Howarth <howarth@bromo.med.uc.edu>
PR target/26792:
* exception.cc (PERSONALITY_FUNCTION): use _Unwind_GetIP
if HAVE_GETIPINFO not defined.
* stacktrace.cc (_Jv_StackTrace::UnwindTraceFn): Likewise.
(_Jv_StackTrace::getLineNumberForFrame): Likewise.
* configure.ac: use GCC_CHECK_UNWIND_GETIPINFO.
* aclocal.m4, configure, include/config.h.in, Makefile.in:
Rebuilt.
