Great news! And special thanks for fixing bug 540...

Unfortunately, this code (which appears in derelict) broke

-
version(Windows)
  extern(Windows):
else
  extern(C):

Declaration expected, not 'else'
-

Looking around in the spec, I can not find where the StorageClass: syntax is
defined, so maybe it is supposed to be illegal?

Cheers,
Christian
