|laziness, impatience, and hubris|
I got around to installing 5.8.7 and attempted a rebuild of Object::InsideOut, and got the same failures as before, but this time noted that Makefile.pl produced a warning
I tracked that down to the XS version not having been built/distributed as a part of 5.8.7. So I pulled the CPAN version and attempted to build it, and it refused to attempt to build. That I tracked down to the can_cc() apparently returning false.
Cutting a long story short(ish), harcoding the $do_xs var in the Scalar-List::Util Makefile to true, allowed me to cleanly build the xs version, making the isweak() and other XS-only functions available. With that, O::IO builds, tests and runs clean.
Why can_cc() fails I cannot work out, but...if you get other failures on Win32, that would be a good starting point.
I should probably raise a bug report against something, but what? AS 813, SL::U or MakeMaker?
