Hi Greg,
Thanks again for maintaining ghc in macports!
I tried installing ghc through macports. Unfortunately, the build
failed with the following error message below. I'd be happy to send
you a complete log, if you think it would help. Many thanks,

Hi,
my binary distribution
http://www.haskell.org/ghc/dist/6.8.2/maeder/ghc-6.8.2-i386-unknown-linux.tar.bz2
creates binaries that fail on some i386 linux boxes with:
timer_create: Invalid argument
I've built the distribution with
gcc version 4.1.2 20061115 (prerelease) (SUSE Linux)
and the file

It's probably not worth quibbling about the issue I raised about "foo.h
&foo" i
If, following this thread, you conclude that GHC should do something different
than what it does, can you submit a Trac ticket? With a small example?
Thanks

No, it's fine. compress is indeed monomorphic, but since it's called at
exactly one type, namely Char, so it gets the monomorphic type [Char] ->
[Char]. That is what the Haskell Report says. (Or tries to.)
