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.
