Ah, cool you found it. I was just about to point you to my archive, so
you don't have to go through the process of lifting it out of gcc
yourself, and we can perhaps maintain that "split out" version
collaborativly.

No, sorry. I'm ATM busy with University, but after that I'm going to
look at several issues G-Wrap has on non-x86 (see [0], starting with
the 1.9.3-2 logs). There is the possibility that libffi has to do with
it, but at least on ia64, it seems to be Guile's fault.

Does darcs have something like Arch configs[1]? I use these to include
libffi into the G-Wrap tarball.
