[Win32] Failing tests as of perl-5.33.5 onwards

[sisyphus]

No problems with Path-Tiny-0.116 on perl-5.33.4 and earlier - irrespective of ivtype and nvtype. However, with perl-5.33.5, perl-5.33.6, and current blead (up to commit 01900a5f, at least) the test suite for Path-Tiny-0.116 is producing the following output:

"C:\perl-5.33.7-830\bin\MSWin32-x64-multi-thread\perl.exe" "-MExtUtils::Command::MM" "-MTest::Harness" "-e" "undef *Test::Harness::Switches; test_harness(0, 'blib\lib', 'blib\arch')" t/*.t

[xdg]

This seems likely to be related to the 5.33.5 Windows symlink change.

[xdg]

@sisyphus I don't have a windows box handy to test. Would you mind trying the windows-symlinks branch and letting me know if that gets tests passing again?

[sisyphus]

No problem, @xdg. The windows-symlinks branch passes all tests. Looks good !! (The "master" branch fails, as reported earlier.)

[xdg]

Thank you very much!
