Merged revisions 45277-45280 via svnmerge from https://svn.boost.org/svn/boost/branches/unordered/trunk ........ r45277 | danieljames | 2008-05-11 14:09:05 +0100 (Sun, 11 May 2008) | 2 lines Put the prime number list into a template so that they (hopefully) only get included once. ........ r45278 | danieljames | 2008-05-11 14:12:27 +0100 (Sun, 11 May 2008) | 2 lines Add a quick explanation for an odd looking constructor. ........ r45279 | danieljames | 2008-05-11 14:12:37 +0100 (Sun, 11 May 2008) | 2 lines No need to include the exception objects in helpers/strong.hpp. Now helpers on depend on the forwarding header from the objects. ........ r45280 | danieljames | 2008-05-11 14:14:31 +0100 (Sun, 11 May 2008) | 1 line Instead of comparing potentially dangling pointers in move_tests check if any objects have been constructed. ........
