The GNU C Library implements much of the POSIX.1 functionality in the
GNU/Hurd system, using configurations i[34567]86-*-gnu.
When working with Linux kernels, the GNU C Library version 2.4 is
intended primarily for use with Linux kernel version 2.6.0 and later.
We only support using the NPTL implementation of pthreads, which is now
the default configuration. Most of the C library will continue to work
on older Linux kernels and many programs will not require a 2.6 kernel
to run correctly. However, pthreads and related functionality will not
work at all on old kernels and we do not recommend using glibc 2.4 with
any Linux kernel prior to 2.6.

All Linux kernel versions prior to 2.6.16 are known to have some bugs that
may cause some of the tests related to pthreads in "make check" to fail.
If you see such problems, please try the test suite on the most recent
Linux kernel version that you can use, before pursuing those bugs further.
Also note that the shared version of the libgcc_s library must be
installed for the pthread library to work correctly.
The old LinuxThreads add-on implementation of pthreads for older Linux
kernels is no longer supported, and we are not distributing it with this
release. Someone has volunteered to revive its maintenance unofficially
