I've modified some places (that check for an absolute path) in the MinGW
port to read (path[0] == '/' || path[1] == ':'). I don't think that it's
necessary that you cater for this case in your code - I'll take care of
it in the MinGW port. Of course, a hint that there is another place to
watch out for, or even better a test case in t/, is most appreciated.

I still hope to find some time to rework the MinGW port. Then such
details will be hidden behind a is_path_absolute() function. Or maybe
getcwd_or_die() ;)
