Summary: gmp's memory management

Initial Comment:
Simon M,

I assume ghc allocates the lumps of gmp integers still
on ghc's heap, making it impossible (or very awkward)
to interface to C libraries that use gmp themselves. Is
there a chance that you could use the default memory
allocator for lumps starting from ghc 6.4? That would
make my life much easier.

Thanks,
Axel.

It's a known problem that you can't use GMP via the FFI from
your Haskell code in GHC, or use a C library that internally
uses GMP.  We should really use a private version of GMP
with function names that don't overlap, or better still
replace GMP altogether.

I don't think this is going to get fixed for 6.4, I'm afraid.
