I've got two very simple programs that draw a very simple picture using

Hi Claude,
I suspected that the issue could be about unsafe foreign imports - all

I compiled myself a version of cairo bindings with the rectangle and

Any idea how to debug why all the GMP calls?
I'm looking at even the auto-generated source for cairo bindings, but I

I made a small change in Types.chs and got my original cairo-binding-based

that I used multiparameter type classes.

A simple {-# INLINE cFloatConv #-} helped to the same extent!
Axel, I think this change should be pretty easy to incorporate, and it

Hello,
When I tell cabal-install to build shared libraries (with Shared: True in
