building cvs head with cygwin/mingw: ghc-inplace tries to execute directory?

[Claus Reinke]

on windows xp sp2 with cygwin:

- installed latest alex,happy,haddock from binaries on Sven's page
    (should this be mentioned in the building guide?
     http://www.aedion.de/haskell/ )

- installed ghc 6.4, using msi in download area

- fetched fresh copy of fptools from cvs, to c:/fptools/fptools

- followed build instructions for mingw-build

    + installed msys, but added glut
        (you might want to mention this in 13.4; also, is there no
         way to use ghc's copy of mingw instead of a separate one?)
    + autoreconf
    + ./configure --host=i386-unknown-mingw32 --with-gcc=c:/mingw/bin/gcc
    + copied mk/build.mk.sample and added
        'BuildPackageGHC=YES' in mk/build.mk
    + make 2>&1 | tee <somewhere>/make.log

myrtle$ tail -f make.log

I don't have access to the files at the moment (only redirected the make
log to a machine I can see), but it looks as if ghc-inplace simply tries to
execute a directory?

suggestions?
