# The Nix `gcc' stdenv.mkDerivation is not directly usable, since it doesn't
# know where the C library and standard header files are. Therefore
# the compiler produced by that package cannot be installed directly
# in a user environment and used from the command line. This
# stdenv.mkDerivation provides a wrapper that sets up the right environment
# variables so that the compiler and the linker just "work".
