I don't know if Pierre picked up on something else (or maybe just looked
at the cygcheck output) but a clue was the fact that path_conv::check
kept inspecting components of the path even after a valid path was
detected.  I was working my way there when I wisely decided to check the
mailing list and saw Pierre's insight.  It's supposed to stop looking at
the path once it finds a valid path, except in the case of non-relaxed
case checking, i.e., this is one of a few slowdowns in the case checking
code.
