--- Comment #19 from Martin Jambor <jamborm at gcc dot gnu.org> ---
HJ, how do I configure build an x32 gcc?  I have working x32 debian
chroot environment but building gcc fails with:

checking for int64_t underlying type... long long
configure: error: error verifying int64_t uses long long
Makefile:4053: recipe for target 'configure-gcc' failed

is there a howto somewhere?  Thanks.
