I want to publish a module on CPAN that absolutely requires support for 64-bit integers. It is chess software, and there is really no work around that requirement.

I can use Config.pm in my Makefile.PL and bail out if there is not support for 64 bit but then I'll get spammed by CPAN testers running tests on 32-bit Perls. Is there any way to avoid this?

And what exact configuration option should I check?
