The gcc-wrapper doesn't wrap 'cpp'. This breaks some software (such as
Buildroot) because the 'cpp' they get come from the non-wrapped gcc
package which doesn't know about any standard include paths.
gcc-cross-wrapper is untested.
This comes from:
svn diff ^/nixpkgs/trunk/@18255 ^/nixpkgs/branches/stdenv-updates/ > diff
patch -p0 < diff
and then adding into svn all files new from the patch.
trunk@18255 comes from the last time I updated stdenv-updates from trunk.

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'

builders. These are redundant now.
* Inlined some trivial builders.
* Removed a few explicit setup-hook creations. This is done
automatically now if setupHook is set.
* Deleted the initscripts package. NixOS doesn't use it anymore.
svn path=/nixpkgs/branches/stdenv-updates/; revision=15276
should fix previous problems with GCC 4.3 in compiling C++ code
where e.g. <cassert> has to appear before <assert.h> in the search
path due to the former's use of #include_next. The previous "fix"
broke compilation of C code by placing the C++ include directory
before the Glibc include directory (which would barf on
e.g. <complex.h>, which appears in both).
svn path=/nixpkgs/branches/stdenv-updates/; revision=13806
* Removed substitute, it's part of the generic builder now.
* stdenv-initial (Linux): use the real generic builder script. This
does require that sed is in the path of the builder of the initial
stdenv.

we use the GCC wrapper in a user environment, the wrong assembler
will be called. This is not usually a problem, but sometimes it is
(e.g., when using G++ 4.1.1 with binutils 2.16 or so).

Glibc. This is useful when building GCC.
* gcc-wrapper: the dynamic linker has a different name on x86_64 and
powerpc.
* gcc-wrapper: "glibc" -> "libc", because someday we might support
different C libraries.
* gcc: don't do a multilib build (e.g., 32-bit support on x86_64),
don't need it.
* gcc: merge in support for static builds.
* gcc: various simplifications in the compiler/linker flags, hope they
work.

this contains mostly Armijn's pure stdenv-linux.
* After unpacking the statically linked GCC, patch all store paths to
/nix/store/ffffffffffffffffffffffffffffffff. Ugly hack to prevent
undeclared references but it works.
* We don't need Glib's dynamic libraries in the first bootstrap stage;
delete them. Actually the downloaded Glibc binary is only needed
for building Glibc, since GCC needs a C compiler to build some
programs in `configure'. So static linking is fine for that. Maybe
it would be better to patch `configure' so that we don't need a
pre-built Glibc at all.
* Set the svn:executable property on `cp' and `patchelf'.
* In Glibc, revert to LinuxThreads. Maybe NPTL will work, but TLS
support is a problem.
* Delete most Glibc patches; they're no longer needed since the branch
updated it to 20050110.
* Some cleanups.

libgcc of the gcc being built, not the gcc building it.
* Only include a directory in the rpath of an executable/library if it
is actually used. Before, the `/lib' directory of every build input
was added to the rpath, causing many unnecessary retained
dependencies. For instance, Perl has a `/lib' directory, but most
applications whose build process uses Perl don't actually link
against Perl. (Also added a test for this.)
* After building glibc, remove glibcbug, to prevent a retained
dependency on gcc.
* Add a newline after `building X' in GNU Make.

On the downside, the build process of stdenvLinux builds gcc 9 times
(3 x 3 bootstrap stages). That's a bit excessive.
svn path=/nixpkgs/trunk/; revision=880
* Make builders unexecutable by removing the hash-bang line and
execute permission.
* Convert calls to `derivation' to `mkDerivation'.
* Remove `system' and `stdenv' attributes from calls to
`mkDerivation'. These transformations were all done automatically,
so it is quite possible I broke stuff.
* Put the `mkDerivation' function in stdenv/generic.
svn path=/nixpkgs/trunk/; revision=874
checked whether absolute paths passed to gcc/ld refer to the store,
which is wrong: they can also refer to the build tree
(/tmp/nix-...).
* Less static composition in the construction of stdenv-nix-linux:
gcc-wrapper and generic are now passed in as arguments, rather then
referenced by relative path. This makes it easier to hack on a
specific stage of the bootstrap process (before, a change to, e.g.,
generic/setup.sh would cause all bootstrap stages to be redone).

- gcc/ld-wrappers have been factored out into a separate
derivation. This allows a working gcc to be installed in the user
environment. (Previously the Nix gcc didn't work because it
needed a whole bunch of flags to point to glibc.)
- Better modularity: packages can specify hooks into the setup
scripts. For instance, setup no longer knows about the
PKG_CONFIG_PATH variable; pkgconfig can set it up instead.
- gcc not longer depends on binutils. This simplifies the bootstrap
process.
