# 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.
# stdenvType exists to support multiple kinds of stdenvs on the same
# system, e.g., cygwin and mingw builds on i686-cygwin. Most people
# can ignore it.
