I remembered something odd with how windoze handled the long paths in DOS boxes (older versions, as win2K DOS box works normally). When paths had spaces you could enclose it in quotes, when the path was too long it would chop it off at six characters and append ~1 as below:

I entered the path in this fashion in the CPAN config for make and make seems to make ;-)
Use dir /x to get the real short name which "may not" have a ~1.
