But the problem is not only that it emits a reference: it is
duplicating the code on every file that includes the header! Every
file in ECL includes gmp.h and due to the extern __inline__
declaration, those functions are being compiled and externalized on
every single file. Then the linker complains about those multiple
references.

I had a look and the compiler in that particular cluster is very new,
4.4.1. I wonder whether behavior w.r.t. extern inline declarations has
changed recently, because I do not have this problem with the same
headers in other platforms and older versions of gcc (<= 4.3)

In any case, I can report that ECL + MPIR is doing the job.
Unfortunately I have problems with my usb modem and can not get a
stable connection to the Solaris boxes to see a build finish. Will try
later on or tomorrow.
