[boost] Linux RC_1_31_0 regression test questions

Looking at http://boost.sourceforge.net/regression-logs/cs-Linux-RC_1_31_0.html to make sure we are in good shape for RC2 from the Linux perspective, I've got some (probably dumb) questions: * gcc 3.4 20040124 (prerelease) has 21 errors compared to 3 errors for gcc 3.3.1 and 3.3.2. Has anyone looked at the 3.4 errors and reported them to the appropriate gcc or Boost lists? Here are the three tests failing gcc 3.3.1 and 3.3.2: * iterator interoperable_fail * python embedding * type_traits is_abstract_test Do any of these raise alarm bells? Or are they all to be expected? --Beman
