Yeah, I've already noticed that and fixed it in my repo. The deal is that prior to 5.23.2 the core headers didn't define U64 for modules, so any module needing it had to define it itself. But from 5.23.2 onwards the core does define it, so there's now a duplicate typedef for those modules if they're not updated. A duplicate typedef is legal C11, but not legal C99 or earlier. So this only fails on Perl 5.23.2 or higher with a pre-C11 compiler. The fix is for the module to make its U64 definition dependent on the Perl version. I'm doing this: #if defined(HAS_QUAD) && !PERL_VERSION_GE(5,23,2) typedef U64TYPE U64; #endif /* HAS_QUAD && <5.23.2 */ -zefram
