Summary: CompManager confused by not compiled .hs files

Initial Comment:
Version: CVS HEAD from 09/02/2001

When I compile a module 

  import Ptr
  main = print 42

with

  ghc -c -package lang Main.hs

then ghc causes trouble iff I have a file with the name `Ptr.hs' in the current directory.  Instead of using `Ptr'
from -package lang, ghc complains about a missing file `Ptr.hi'.

I can imagine why this is happening and it probably even makes sense for the interactive system; however, it is counter-intuitive for the batch system and diverges from the behaviour of 4.08.

This situation occurs easily in a setup, where I have a version Ptr.hs that my Makefiles arrange to compile in when using 4.08, but omit in favour of the module coming with -package lang when using 4.11.

Fixed.  ghc -c now uses a different module-searching 
algorithm from GHCi; namely, it looks for .hi files only 
whereas GHCi (and ghc --make) looks for source files.

This is still present in 5.02, and it does not have to be
the current directory - any directory in the import path
will do.

I will attache a tar file, if SourceForge will let me,
showing how to reproduce the bug in its stronger form. If
SourceForge will not, interested persons may email me for
it.

BTW I could not log-in to SourceForge to submit this, even
though I have a SourceForge account!
