# The Nix `gcc' derivation 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
|
|
# derivation provides a wrapper that sets up the right environment
|
|
# variables so that the compiler and the linker just "work".
