-Supported Configurations

-The GNU C Library currently supports configurations that match the
-following patterns:

-     arm-*-linux
-     cris-*-linux
-     hppa-*-linux
-     iX86-*-gnu

-     s390x-*-linux
-     sparc-*-linux
-     sparc64-*-linux
-     x86_64-*-linux
-
-   Former releases of this library (version 2.1 and/or 2.0) used to run
-on the following configurations:
-
-     arm-*-linuxaout
-     arm-*-none
-
-   Very early releases (version 1.09.1 and perhaps earlier versions)
-used to run on the following configurations:
-
-     alpha-dec-osf1
-     alpha-*-linuxecoff
-     iX86-*-bsd4.3
-     iX86-*-isc2.2
-     iX86-*-isc3.N
-     iX86-*-sco3.2
-     iX86-*-sco3.2v4
-     iX86-*-sysv
-     iX86-*-sysv4
-     iX86-force_cpu386-none
-     iX86-sequent-bsd
-     i960-nindy960-none
-     m68k-hp-bsd4.3
-     m68k-mvme135-none
-     m68k-mvme136-none
-     m68k-sony-newsos3
-     m68k-sony-newsos4
-     m68k-sun-sunos4.N
-     mips-dec-ultrix4.N
-     mips-sgi-irix4.N
-     sparc-sun-solaris2.N
-     sparc-sun-sunos4.N
-
-   Since no one has volunteered to test and fix these configurations,
-they are not supported at the moment.  They probably don't compile;
-they definitely don't work anymore.  Porting the library is not hard.
-If you are interested in doing a port, please contact the glibc
-maintainers.  Start at `http://www.gnu.org/software/libc/' and read the
-references there on how to go about getting involved and contacting the
-developers.
-
-   Valid cases of `iX86' include `i386', `i486', `i586', and `i686'.
-All of those configurations produce a library that can run on this
-processor and newer processors.  The GCC compiler by default generates
-code that's optimized for the machine it's configured for and will use
-the instructions available on that machine.  For example if your GCC is
-configured for `i686', gcc will optimize for `i686' and might issue
-some `i686' specific instructions.  To generate code for other models,
-you have to configure for that model and give GCC the appropriate
-`-march=' and `-mcpu=' compiler switches via CFLAGS.

+This directory contains the version 2.4 release of the GNU C Library.
+
+The GNU C Library is the standard system C library for all GNU systems,
+and is an important part of what makes up a GNU system.  It provides the
+system API for all programs written in C and C-compatible languages such
+as C++ and Objective C; the runtime facilities of other programming
+languages use the C library to access the underlying operating system.
+
+In GNU/Linux systems, the C library works with the Linux kernel to
+implement the operating system behavior seen by user applications.
+In GNU/Hurd systems, it works with a microkernel and Hurd servers.
+
+Version 2.4 is the first release after a long period of development, and
+introduces changes to the API and a new ABI for all configurations.  It
+has been tested and deployed in new production systems, but should still
+be considered somewhat experimental.  The stable 2.3 release series
+continues to be maintained, and implements a widely-deployed ABI.
+Version 2.3.6 is available, and we will release 2.3.7 with more bug fixes.
+
+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.
+
+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
+for at least a short time for the benefit of those using Linux kernels
+older than 2.6, but a working version is not presently available.  When
+it is in working condition, we will make it available alongside future
+glibc releases.  LinuxThreads will not be supported.
+
+The GNU C Library supports these configurations for using Linux kernels:
+
+	i[34567]86-*-linux-gnu
+	x86_64-*-linux-gnu
+	powerpc-*-linux-gnu
+	powerpc64-*-linux-gnu
+	s390-*-linux-gnu
+	s390x-*-linux-gnu
+	ia64-*-linux-gnu
+	sparc*-*-linux-gnu
+	sparc64*-*-linux-gnu
+
+	alpha*-*-linux-gnu	Requires Linux 2.6.9 for NPTL
+	sh[34]-*-linux-gnu	Requires Linux 2.6.11
+
+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-2.4 distributed separately in the
+same place where you got the main glibc distribution files.
+Currently these configurations are known to work using the `ports' add-on:
+
+	arm-*-linux-gnu		Requires Linux 2.6.15 for NPTL, no SMP support
+	arm-*-linux-gnueabi	Requires Linux 2.6.16-rc1 for NPTL, no SMP
+	mips-*-linux-gnu	Requires Linux 2.6.12 for NPTL
+	mips64-*-linux-gnu	Requires Linux 2.6.12 for NPTL
+
+The ports distribution also contains code for other configurations that
+do not work or have not been maintained recently, but will be of use to
+anyone trying to make a new configuration work.  If you are interested
+in doing a port, please contact the glibc maintainers; see

-Valid cases of @samp{i@var{x}86} include @samp{i386}, @samp{i486},
-@samp{i586}, and @samp{i686}.  All of those configurations produce a
-library that can run on this processor and newer processors.  The GCC
-compiler by default generates code that's optimized for the machine it's
-configured for and will use the instructions available on that machine.
-For example if your GCC is configured for @samp{i686}, gcc will optimize
-for @samp{i686} and might issue some @samp{i686} specific instructions.
-To generate code for other models, you have to configure for that model
-and give GCC the appropriate @samp{-march=} and @samp{-mcpu=} compiler
-switches via @var{CFLAGS}.
