cpm Failures on 5.12 windows

[theory]

See this run, with this bit:

cpm install --global --verbose --show-build-log-on-failure --no-test Locale::[email protected]

Leads to these errors:

Don't know if it's an old version or something about its configuration is off. Appears to work fine on 5.14 and later (can't speak to earlier versions).

I have the issue with Windows and Perl v5.10 and v5.12. For all other major Perls starting from v5.8 cpm works for Windows and MacOS.
