I don't know the details of that software and don't have the sources. 
But it needs to access the directory with the Windows API and somehow 
derives the Windows path back from /usr/lib which then doesn't work 
because /usr/lib doesn't exist for Windows while /lib does.
For this reason, I would suggest and appreciate if cygwin_conv_path 
disregards the mount point for its mapping in order to provide a more 
consistent match which also works with a "manual round-trip".
