OK I did. It work on a basic test at least :
gcc-3.4 -v -static -I/usr/include/nptl -L/usr/lib/nptl t3.c -o t3 -lpthread

The futex system calls above clearly sho that I'm indeed using the NPTL
implementation for the posix threads library and it seems to work.
To be sure, I would however recommand to run the openposix test suite
and compare the results as I did when releasing my own static version to
my customers ...
