Weel as I said, I got ghc --make to work by giving it a pair of extra
arguments, which I suppose I would have to do with hmake as well.

My main arguments for using ghc --make instead of hmake is that I can
avoid the startup time for ghc (hmake calls it once per source file),
and that it does more fine-grained dependency, so that if the interface
of a module is unchanged, modules that depend on it need not be
recompiled. Maybe the last one is fixed now.

And the solution I gave (-pgmF) also works for ghci (it probably invokes
the same functions as --make does).

But since hsc2hs is (somewhat) integrated into ghc, I see no reason
(apart from the fact that someone has to implement it of course) why
--make shouldn't be able to handle .hsc files automatically without
extra arguments.

Regards,
