Consider the following two Modules:
File A.lhs:
==============
> module A where
> data A a = MkA a
==============
File B.lhs:
==============
> module B where
> import qualified A
> type A a = A.A a --- Problem!
==============
ghc-4.03 (current sources) complains while compiling B.lhs:
B.lhs:5: parse error on input `.'
(Renaming all the types does not make a difference.)
Both ghc-3.02 and Hugs 98 (May 1999) are happy with these modules,
and I also cannot detect anything in the Haskell98 report
justifying this rejection.

P.S.: When I call ``make tags'' from fptools/ghc/compiler,
the output consists mostly of error messages concerning the absence
of hsp:
cpp: output pipe has been closed
sh: /var/tmp/kahl/ghc/current/build-4.03/ghc/compiler/hsp: No such file or directory
