This one is a bit of a pain.  Some library modules have several -#include
options.  To turn that into code that conforms to the FFI spec, you have
to collect those #include's in a new header file, and add that to each
of the foreign imports; if those already have includes, more munging
is required.

If you've decided that the method provided by the FFI spec (though
sufficient) is too clunky to use, perhaps it should be changed.

We have discussed this particular point for a quite a
while.  The conclusion was that it is infeasible to provide
the flexibility of CPP; hence, the FFI just provides the
bare minimum and anything more complicated requires the
programmer to write a custom header and include that in the
FFI declarations.

What I am curious about is point (b).  In what respect does
GHC not support it well?

Cheers,
Manuel

Cross-module inlining of a foreign import with a #include attached
doesn't work: passing the #include info with the Id in the interface
file isn't implemented.  So we currently disable cross-module inlining
of foreign imports if they have a #include attached.  

I'm really not keen on putting #includes in FFI declarations (as I've
expounded several times on the FFI list before).  Doesn't Hugs have
something similar to -#include that can be used instead?

Cheers,
	Simon

No, but I'm starting to agree that it should, or rather that the FFI spec
should.

Actually, you could use Hugs' ability to pass arbitrary command line arguments 
to the compiler to do so.  (This would use the gcc specific -inline command 
line flag.)

But I would rather see the existing ffi spec implemented or the ffi spec 
changed to allow some kind of 'foreign include' declarations than use this
crufty little feature.
