Revision: 1.56
Committed: Mon Dec 18 02:35:01 2006 UTC (17 years, 5 months ago) by root
Content type: text/plain
Branch: MAIN
Changes since 1.55: +4 -2 lines
Log Message:
- remove recycle_tmp_maps setting (hardwired to true)
- replace object->flags by std::bitset, seems to be way
  more efficient, for some unexplainable and not looked-into reason.
  its way cleaner, too...
