You don't have the sources?  Of a Cygwin application?  That's a problem
licensing-wise, and that makes me much less sympathetic.

And then again, if it's a Cygwin application, it has a bug, and the bug
should be fixed in that software, so you should file a bug with them.

OTOH, if it's, in fact, not a Cygwin application, then any changes to
cygwin_conv_path are moot.
