Hi all.  Attempting to compile a mutually recursive pair of modules,
with various inferface file jiggery-pokery, I encountered the following:


swift.ucc.ie:~/freq: make G61.o
make: Circular G61.hi <- G61.o dependency dropped.
rm -f G62.o
ghc-2.01 -c G62.hs -H30m  -K2M         -recomp -fglasgow-exts -cpp -hi-diffs 
-ansi -syslib ghc 
ghc-2.01:compile:Output file G62.o doesn't exist
 
An interface has an implicit need of G62.HappyAbsSyn; assuming this module will 
provide it.

panic! (the `impossible' happened):
        tcLookupTyCon:G62.HappyAbsSyn

Please report it as a compiler bug to [EMAIL PROTECTED]

make: *** [G62.o] Error 1


I suspect it may be caused by an incorrect Module name in the referenced
interface file.

Alex.
