New Revision: 48586
URL: http://svn.boost.org/trac/boost/changeset/48586
Log:
Optimized Boost Build's generator selection related viable-source-types-for-generator-real() rule. Now it exits more quickly in case it detects that any source type is a viable source type and so there is no need to look for more viable source types.
