Hi all,
now after this commit:
https://gcc.gnu.org/ml/gcc-cvs/2015-05/msg01107.html
(Thank you John!)
I can submit this patch which brings working signal handling support for
FreeBSD amd64/i386. The libjava test suite passes w/o failure now.
Results can be found on the list.
Is this ok for trunk?
Thanks,
Andreas
