I can confirm that the patch allows me to build on drive d:
while /mingw only exists on drive c:, so that workaround
solves my recent issue (and should mean that other people's
build no longer work by accident only, reducing chances for
obscure breakage). Neil: does it also render your special 
build settings obsolete?

In the long run, I'd still recommend not to change mingw's
internal directory layout for the bits included in ghc distributions
(distrib/prep-bin-dist-mingw is doing those changes), so that 
gcc can find its files without extra options. I've added a link to 
this thread to http://hackage.haskell.org/trac/ghc/ticket/1502 ,
in case this doesn't get fixed for the current release.

Thanks,
Claus
