# This test *must* be run prior to releasing any build of either stdenv or the
# gcc that it exports! This check should also be part of CI for any PR that
# causes a rebuild of `stdenv.cc`.
#
# When we used gcc's internal bootstrap it did this check as part of (and
# serially with) the gcc derivation. Now that we bootstrap externally this
# check can be done in parallel with any/all of stdenv's referrers. But we
# must remember to do the check.
