The .hi files in include/ for the standard prelude and libraries
are static.  They are not recreated or overwritten during the build
process.  This is partly because they are needed to bootstrap the
build, and partly because there are some special hand-tweaks to these
versions of the files (some for performance, some possibly also to
avoid bugs).  Think of them as being like ghc's .hi-boot files.

By contrast, those for the hierarchical libs (under include/packages/)
are indeed copied directly during the build.

You can probably just copy the relevant file (Foreign.hi?) to the
include directory, and check it into CVS if it works.
