Hi, I complained late last week that GHC failed to build because ghc-inplace couldn't do anything more complicated than print its version number. I tried again on a clean machine, this time remembering to replace Cygwin's sh.exe with bash.exe, and mounting C:\mingw as /mingw and C:\mingw\include as /mingw/mingw32/include. GHC apparently builds now (although the build hasn't finished... I've only 256 MB RAM and serious thrashing goes on when the build is doing this xargs ar thing!). Thanks for your help and patience!
