No; for some reason, after "make clean; make"  the compile goes straight 
for hat.c and then for the above Haskell file. Rerunning "./configure" 
after deleting the targets directory fixed the maze of Makefiles, and 
ghc is building the Haskell source right now.

I think I understand what caused my problem. On Mac OS X, there is no 
/usr/bin/gcc; even though Apple's cc is gcc, it's called /usr/bin/cc. 
"CC=gcc" is hardcoded into targets/<target>/config.cache, but 
"configure" never checks for gcc; I guess that it assumes that if 
there's a working ghc there's a working gcc. Anyway, the first time I 
tried to build, the Haskell sources built fine but the build failed on 
"hat.c" because hmake couldn't find gcc. I edited config.cache by hand, 
ran "make clean", and restarted the build, but "make clean" didn't clean 
enough. Perhaps the "make clean" target should delete the targets 
directory?

Thanks for the info; do you have an ETA on ghc-5.04.1? I'm unfamiliar 
with the ghc build process, but I understand that it involves some sort 
of bootstrapping like the build process of gcc. Will I be able to use my 
ghc 5.04 to build a new ghc 5.04.1 when it is released? Will it be 
compatible with gcc 3.1?
