I need to quote some postings i did here a few weeks ago. Did you miss them? the wcrafty-18.15.exe version which is on the ftp site from bob is intel c++ 6.0 by the way. it has bugs in P4 optimizations which possibly could cause a slower executable than the intel compiler 6.0 compiler without -G7 (which is P4 optimization) which is used for wcrafty-18.15.exe, which is slower than alternatives.
