[project @ 2004-11-09 17:21:58 by simonmar]

Add a compatibility library, which will mean that we can make use of
brand new libraries directly in GHC and the tools even when compiling
with older versions of GHC.  The library just consists of stubs that
#include code from fptools/libraries.

This isn't wired up to the build yet.
