[nhc-bugs] Qualified imports

[Ralf Hinze]

In a larger project I use qualified imports a lot. Now, when I
try to compile the program with nhc98 I get ...

...
nhc98  -98  -I/home/ralf/Haskell/LibRH/nhc98/ -P/home/ralf/Haskell/LibRH/nhc98/
 -c -o Future.o Future.lhs
Warning: when renaming newtype of imported newtype:
  Real type of OrdUniqListFM.FM is not visible.
  I might get boxed/unboxed info wrong.
nhc98  -98  -I/home/ralf/Haskell/LibRH/nhc98/ -P/home/ralf/Haskell/LibRH/nhc98/
 -c -o LR0.o LR0.lhs

====================================
        Error when renaming::
Identifier unionMany defined 3 times.
Identifier fromList defined 3 times.
Identifier lookup defined 2 times.
Identifier union defined 3 times.
Identifier elem defined 2 times.
Identifier length defined 3 times.

This is basically true. However, the definitions reside in different modules that
are imported qualified.

Unfortunately, I wasn't able to boil down the error (all the toy programs I came
up with work fine). I'll send you the files, if you have time to chase down the bug.

Cheers, Ralf
