# description expects the runtime library to be installed in

# result, it would detect the unwrapped GNAT as a proper
# compiler which is unable to produce working binaries.
#
# Our compiler description is very similar to the upstream
# GNAT description except that we use a symlink in $out/nix-support
# created by the cc-wrapper to find the associated runtime
# libraries and use gnatmake instead of gnatls to find GNAT's
# bin directory.
