Changes for version 0.12
- Try to detect if references to "cpow" will not be resolved - and abort the build if this problem is found to exist. (This enables us to avoid some FAIL reports from cpan-testers.)
- Rewrite tests 4 and 5 in t/overload_string.t s that they don't register a fail if the libc bug that causes 'nan nan' to be returned (instead of the correct 'inf inf') is present.
- Math::Complex_C - perl interface to C's double precision complex operations.
