nixpkgs/pkgs/development/compilers/gcc-4.2/no-sys-dirs.patch
Eelco Dolstra b8dae869b3 * Trying to get gcc 4.2.0 to compile... 
* Compute --enable-languages in the Nix expression instead of in the
  builder.
* Pass some flags through the Make command line instead of patching
  the Makefiles.
* gcc: generate code for i686 by default (instead of i386).
* gcc: patch out some references to /lib and /usr/lib.
