Indeed, they were shared.
The thing that caught me is that I have built GCC hundreds of times on
i686/x86_64 with shared, private dir gmp/mpfr/mpc without a problem, so I went
ahead and did the same on this machine; I normally bootstrap on my two main
machines the 4.6 trunk every other day.
Of course I am not claiming I didn't do anything wrong, just that it was not
obvious from the various docs, including platform notes, that it was safer to
use disable-shared or build from the GCC source tree. Anyway, my problem is
fixed, and I know a bit more than yesterday; thanks everybody.
