New Revision: 60768
URL: http://svn.boost.org/trac/boost/changeset/60768
Log:
Fix possible problems when trailing or leading whitespace is added to the env vars used, for example CC and CFLAGS when using the cc toolset. Even though I can't get compilation to fail even with the extra whitespace during building it does seem to fail for some compilers that don't ignore the whitespace arguments. (Fixes #3630)
