Author: gerald Date: Fri Apr 3 21:46:40 2020 New Revision: 530527 URL: https://svnweb.freebsd.org/changeset/ports/530527 Log: Refactor the handling of USE_GCC=any so that it essentially becomes a block of its own as opposed to touching bits and pieces throughout. Use the opportunity to simplify various aspects, such as the static tables describing versions of GCC we support and their initialization. Overall this sheds another 30 lines off what used to me more tricky Makefile code. It should not change behavior.
