This is very strange, because I have tested this and it
worked for me. In fact, if you look at the Makefile in the
c2hs/lib/ directory, then you will see that the `depend'
target moves these troublesome files into a subdirectory
before compilation (called ghc411hackdir).
Is it possible that you used the same build tree to compile
with 4.08 first and then re-compile with 4.11? This won't
work, because of the hack mentioned above.
In fact, I think, this is a bug in ghc 4.11 - I have filled
it as bug #131631 in the bug tracker.
