unwind-pe.h in gcc trunk doesn't compile

[Per Bothner <per at bothner dot com>]

I got a failure bootstrapping the trunk (configured with
-enable-languages=c++,java):

Changing
#if __cplusplus
#define __gxx_abort std::abort
to
#if 0 //__cplusplus
#define __gxx_abort std::abort

lets exception.o be built
