This does work ... only question now, is will it cause issues on a
system compiled with this gcc, and another gcc (3.4/whatever) is
installed that do not export these functions ?

Also, this only occurs with current glibc CVS, with NPTL (0.48-0.52).
I have not been able to test with linuxthreads, but it works fine
with a glibc snapshot of 2003-05-27/9 that also use NPTL (0.38).
