As Levente explained Cog has a different but compatible implementation.  You
should use the source produced by the ReentrantIA32FFIPlugin (which will
still produce code in src/plugins/SqueakFFIPrims/SqueakFFIPrims.c and
depends on the support code only in
http://www.squeakvm.org/svn/squeak/branches/Cog/platforms/Cross/plugins/SqueakFFIPrims,
not the platform-specigic directories (e.g.
platforms/unix/plugins/SqueakFFIPrims platforms/win32/plugins/SqueakFFIPrims
which is not used).
