Hi,

this patch fixes used exception-mechanism for SEH-enabled targets,
which are requesting for SjLj-exception-mechanism.
See also patch for libgcc.

ChangeLog

2012-11-25  Kai Tietz

	PR target/55445
	* libsupc++/eh_personaltity.cc (__SEH__): Additional check
	for not being SjLj.

Tested for multilib i686-w64-mingw32, and x86_64-w64-mingw32 targets.
Ok for apply?

Regards,
Kai
