libgmp comes with an extended config.guess script that features more
accurate CPU detection. Unfortunately, use of that script causes the
configure phase to choose fairly aggressive optimization flags and the
resulting binaries might not work on architectures other than the
machine those binaries were built on.
The standard GNU config.guess script, however, recognizes a CPU type of
'x86' only. Thus, libgmp chooses the following settings:
ABI="32"
CC="gcc"
CFLAGS="-m32 -O2 -pedantic -fomit-frame-pointer -mtune=pentiumpro -march=pentiumpro"
CPPFLAGS=""
MPN_PATH=" x86/p6 x86 generic"

-> No longer install graphical packages if the xserver is disabled.
-> avoid duplication of "mkIf config.services.xserver.enable".

- Do not eval properties on option declarations.
-> mkIf does not mask option declarations if the condition is evaluated to false.

works on Red Hat Linux, i.e. that is based on glibc version 2.5.
Furthermore, this patch fixes a number of gcc 4.3.3 build errors in glibc 2.5
that occur on both x86 and x86_64. The older version of this library is still
useful for running Nix on a Red Hat host. Newer version of glibc fail to detect
the kernel's capabilities correctly (due to mad patches applied to the kernel
by Red Hat).
The individual changes are:
* Re-activated glibc 2.5 in all-packages.nix.
* Fix incomplete header search path in bootstrap tools.
Gcc-wrapper sets "-B<prefix>" to tell the compiler about its installation
root. Unfortunately, the setting doesn't add $gcc/lib/gcc/*/*/include-fixed
to the search path. That directory is required, however, because it contains
the system-specific "limits.h" file, and the glibc 2.5 builds tries to find
that file via #include_next.
* Support intrinsic functions like __signbit() or atof() correctly to avoid
compile-time conflicts.
* Switch to NPTL. Linuxthreads is no longer supported.
* Added a meta attribute to glibc package.
* Updated nixUnstable to version 0.13pre15614 from trunk. The previous version
failed regression tests.
* Fix more strict type checking in binutils since 2.18.50.0.3.
Without this patch, the build failed on x86, saying:
../sysdeps/i386/fpu/ftestexcept.c: Assembler messages:
../sysdeps/i386/fpu/ftestexcept.c:33: Error: suffix or operands invalid for `fnstsw'

ove QEMU (and other NixOS instances that use a remote filesystem like
NFS):
* Don't take down the network interfaces during shutdown.
* Don't try to unmount the Nix store. Usually, this doesn't work
because it's still in use, but on remote filesystems like CIFS the
`-f' umount flag actually works.
