# This file defines the various standard build environments.
#
# On Linux systems, the standard build environment consists of
# Nix-built instances glibc and the `standard' Unix tools, i.e., the
# Posix utilities, the GNU C compiler, and so on. On other systems,
# we use the native C library.

# The native (i.e., impure) build environment. This one uses the
# tools installed on the system outside of the Nix environment,
# i.e., the stuff in /bin, /usr/bin, etc. This environment should
# be used with care, since many Nix packages will not build properly
# with it (e.g., because they require GNU Make).
