[EMAIL PROTECTED] would be a better bet. 
Wolfgang Thaller is Supreme Being for MacOS so I'm cc'ing him too.

| 
| Hi all,
| 
| I'm working with Haskell on MacOS X 10.2.1 using the binaries from
| www.uni-graz.at/imawww/haskell.
| 
| Now, when I compile some code with ghc I get two errors:
| /tmp/ghc617.hc:283: conflicting types for
'GHCziTopHandler_runIO_closure'
| and
| /usr/local/lib/ghc-5.04/include/RtsAPI.h:125: previous declaration of
| 'GHCziTopHandler_runIO_closure'
| 
| Using ghci or compiling with -O2 doesn't show this error.
| 
| Any ideas what's wrong?
| 
| Thanks,
| Markus
| 
| By the way, if there is a list more suited for the subject, please
tell me.

Oh, I like that title!

This is an incompatibility with GCC 3.
There are two ways to work around this:
a) (the recommended way) Switch to GCC 2 using:
sudo gcc_select 2
b) Edit the file /usr/local/lib/ghc-5.04/include/RtsAPI.h. Remove the 
const from the declaration in line 125 and from the declaration next 
to it.
Compilation should now work, but the generated code is worse than with 
GCC 2.

The problem will be fixed in GHC 5.04.2 (There won't be a 5.04.1 for 
Mac OS).
