Subject: [PATCH] * Added the GNU C Library (glibc), a big step towards full
 Nixification of   the build and execution environment.

  This is very useful.  For example, it allows packages built on a SuSE
  8.2 system to run on a SuSE 8.1 system (this is because 8.2 has a newer
  glibc; packages built against it cannot be dynamically linked against
  older glibcs).

  Of course, Fix packages should not directly import glibc since that is
  very system-specific.  Rather, they should import stdenv/stdenv.fix and
  in their build scripts source in $stdenv/setup, which will setup the
  right environment variables.  The idea is that stdenv.fix provides the
  basic C/Unix build environment (C compiler, POSIX utilities, etc.).

  Note that only the ATerm package currently uses this.
