New Revision: 80064
URL: http://svn.boost.org/trac/boost/changeset/80064
Log:
Fixed Boost Jam's internal list structure allocation bug - due to a typo the list_new() operation did not work correctly on systems where LIST * is smaller than LIST (e.g. if LIST * is smaller than OBJECT * or OBJECT * is smaller than an int). Removed code duplication between list_new() & list_alloc(). Contributed by Kohei Takahashi <flast at flast.jp>.
