# bsd.gcc.mk - Support for smarter USE_GCC usage.
#
# Created by: Edwin Groothuis <edwin@freebsd.org>
#
# For port developers:
# If your port needs a specific version of GCC, you can easily specify
# that with the "USE_GCC=" statement. If you need a certain minimal version,
# but don't care if about the upperversion, just the + sign behind
# the version.
#
# For example:
# USE_GCC= 3.3 # port requires GCC 3.3 to build with.
# USE_GCC= 3.4+ # port requires GCC 3.4 or later to build with.
#
# If you are wondering what your port exactly does, use "make test-gcc"
# to see some debugging.
