Bootstrap fails in 32bit libjava on x86_64 Fedora 16 with undefined reference to `__cxa_call_unexpected'

[Uros Bizjak <ubizjak at gmail dot com>]

Hello!

For some reason bootstrap on Fedora 16 fails when compiling 32bit
libjava with undefined reference to `__cxa_call_unexpected':

Digging a bit deeper with:

find . -name '*.o' | xargs nm -o | grep __cxa_call_unexpected
./32/libjava/.libs/prims.o:         U __cxa_call_unexpected

Googling a bit around the net, it looks that this file is wrongly
compiled to use C++ exception code, not java exception code.

Any hints what is going wrong there?

Thanks,
Uros.
