This does not affect other C compilations, and is easily added to e.g. makefiles that use a GHCFLAGS variable... The upcoming GHC 6.4.1 will of course fix this problem. Good to hear that.

I'm on Mac OS 10.4.2, using ghc 6.4 (from the haskell.org .dmg) and gcc 4.0.0. Other wxHaskell programs (the samples and my own experiments) compile without tripping over this. GHC 6.4 is incompatible with gcc 4.0.0 when -O or -via-C is used.

If you compiled wxHaskell yourself, then the problem might also be in wxHaskell (you'd have to recompile it then). The upcoming GHC 6.4.1 will of course fix this problem.

Googling __DISCARD__ led me to ...the binary on the ghc web site has the evil __DISCARD__ mangler problem... on the darwinports bug mailing list, so I guess I'm not the first person to see this. Is there a workaround? Does the Darwin port have the same problem? Should I just work on the many other things I've yet to grasp? Usually ghc works fine.
