You are the first person to try doing this since I severely restructured
the code!

lib is the Windows equivalent of ar, I failed to take this into account.

I entered a variant of your code as a test and made the smallest
possible change to make things work on Linux. This is untested on OS X
or Windows.

The LDC test fails for reasons I cannot suss just now, the DMD and GDC
tests pass.

I have no doubt this is a hack patch, it all needs to be sorted
properly.
