From d191c7d9932b8e8ad96c4345a6ceca67326806ac Mon Sep 17 00:00:00 2001 From: Tim Potter Date: Wed, 21 Sep 2005 05:39:18 +0000 Subject: r10377: Save configuration stuff to sconf.cache so it isn't annoyingly run at every single build. Run 'scons configure=1' or delete sconf.cache to force checks to be re-run. Jelmer, I think this stuff is cached in the .sconf_cache directory but the message is still displayed and it looks like it caches the compiled test object file not the actual result of the test.
