Author: theraven Date: Sat Dec 24 13:28:49 2011 New Revision: 228859 URL: http://svn.freebsd.org/changeset/base/228859 Log: Some GCC-compatibility definitions. Define clang's feature test pseudomacros to always evaluate to 0 if we are using a compiler that doesn't implement them. This lets us use the macros easily in standard headers (e.g. stdatomic.h, which should be the subject of my next commit).
