I find it hard to see how a bug like this could get into a GHC
release, since it appears to break the build. But, I don't know of
anything wrong with the platform I'm running it on, and in general my
setup looks okay (rpm --verify, etc). So, does anyone reproduce this?
I'm running GHC 5.04-1

Yes, that fixes things nicely. Thanks!

In a related issue, it seems that in ghc-5.04 libraries *_hsc.o files
are left out when linking with SplitObjs=YES.
Yes. Actually it's better to not use #def in .hsc files at all, so that
the *_hsc.o files are empty, and rather put auxiliary definitions in the
appropriate header files. I've

I've been playing around with the package mechanism in ghc which
is great.
However it took me quite a while to realise that when I compile
a module (say Foo.hs, for a package) with profiling, the .hi file
must be named Foo.p_hi, and not Foo.hi, when it appears in the
import_dirs directory.
Hi,

I'm being hit by undecidable instances, but I can't see why. I read and
reread the GHC docs on MPTCs, but to no avail. This is what I'm trying to
do:

In Paul Hudak's SOE, I find a definition of expression:

Now this is compelling, but sometimes, I might want to have a function
that takes a variable only, not just any kind of
