Author: gerald Date: Sat Dec 22 21:35:35 2012 New Revision: 309406 URL: http://svnweb.freebsd.org/changeset/ports/309406 Log: Add a new form of USE_GCC, USE_GCC=yes, which generically requests a current version of GCC. This reduces churn for individual ports and further increases consistency (in line with a canonical version that we introduced with GCC_DEFAULT_VERSION earlier on and the older USE_FORTRAN=yes). On the way, make some comments more consistent.
