In GNU/Hurd systems, it works with a microkernel and Hurd servers.
The GNU C Library implements much of the POSIX.1 functionality in the
-GNU/Hurd system, using configurations i[34567]86-*-gnu. The current
-GNU/Hurd support requires out-of-tree patches that will eventually be
-incorporated into an official GNU C Library release.

-When working with Linux kernels, the GNU C Library version from
-version 2.4 on 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. The library is
-unlikely to build without NPTL, or to work on Linux kernels prior to
-2.6. 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.
-
-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.
+When working with Linux kernels, this version of the GNU C Library
+requires Linux kernel version 3.2 or later.
Also note that the shared version of the libgcc_s library must be
installed for the pthread library to work correctly.

-The code for other CPU configurations supported by volunteers outside of
-the core glibc maintenance effort is contained in the separate `ports'
-add-on. You can find glibc-ports-VERSION distributed separately in the
-same place where you got the main glibc distribution files.
-Currently these configurations have code in the `ports' add-on:
-
- alpha*-*-linux-gnu Requires Linux 2.6.9 or newer for NPTL
- am33*-*-linux-gnu Not currently functional
- arm-*-linux-gnueabi Requires Linux 2.6.16-rc1 or newer for NPTL
- hppa-*-linux-gnu Not currently functional without patches.
- ia64-*-linux-gnu
- m68k-*-linux-gnu
- mips-*-linux-gnu Requires Linux 2.6.12 or newer for NPTL
- mips64-*-linux-gnu Requires Linux 2.6.12 or newer for NPTL
- powerpc-*-linux-gnu Software floating point (--without-fp)
