Since you're using LambdaVM you should probably report bugs directly to
me rather than bothering GHC HQ with LambdaVM bugs. I'll let you know
if it isn't my problem.

Indeed it hasn't. I think there are quite a few mingw build problems
lurking in the libraries. I've never actually built LambdaVM on
windows. One of these days I'll get around to it.

You should be able to fix it by changing MutableByteArray# RealWorld to
UArray# RealWorld Word8# and byteArrayContents# to uArrayContents#.

Or you could just run "make way=j" in the libraries dir if you don't
plan on using the same GHC build for generating native binaries. The
java build of the libraries should be fine.
