Yes, putting in a warn() shows it as "use Glib '1.100';".

Actually, it's a very simple line:

I don't think it has anything to do with the shell (cmd.exe, btw), but is 
specific to dmake itself.

There's nothing that sticks out to me in the build command:

The only thing I can think of is that the dll.exp file is somehow being 
translated into a link to dll.exp.dll, but that never seemed to happen to me 
for other XS modules.
