You're right. I should have made a more systematic testing, I merely
tested the r-depends I knew about (talked with Matthias Klose for gcc,
mpfi and mpclib I can take care of). I'll do better next time...

The only incompatible change with the previous version is the removal
of mpfr_random, a function that's labelled "deprecated" for about
seven years. So, let's try to fix what I broke in apron.

After removing the reference to `mpfr_random' in
mlgmpidl/gmp_random.idl then "make clean && make rebuild" apron fails
on "GMP_RND_MAX". The proper fix is not to rely on such an
undocumented feature, but to test against each possible rounding mode
in the assert.

I'll try to provide a patch monday for apron.

Regards,

Laurent.
