code and error related to fedora core 4 glibc static initalization of mutexes

They are correct, some extra warnings just warn even about correct code.
Anyway, http://sources.redhat.com/ml/libc-hacker/2005-07/msg00006.html
should shut these warnings up.

Should be fixed in glibc-2.3.90-3.

When will glibc-2.3.90-3 come out?

The latest, 2.3.5-10.3 as of 24/8/05, exhibits the same problem.

glibc-2.3.90-3 came out more than a month ago, but glibc-2.3.90-* is a rawhide
version (i.e. FC5 development ATM; that's why it has been closed with RAWHIDE).
But glibc-2.3.5-10.3 also includes that fix and certainly doesn't exhibit
the problem for me.
When I fix the testcase a little (s/fprint(/fprintf (stderr, /, plus add return
0; at the end of main), I get:
rpm -qf /usr/include/pthread.h; gcc -W -Wall -O2 fc4-gcc4-mutex.c
