I am very surprised. Is that problem at the gcc level? Does specifying
paths with trailing dir separator cause this problem for gcc in a simple
test case?

If it really is a problem with gcc on windows perhaps ghc can use an
updated gcc in future releases or we could try stripping trailing dir
separators on include dirs in Cabal.
