This is a recent configuration change done by design and has been extensively tested with the new version. EKOPath 4 was just released and we're already in discussion with Sandia to get the test machine updated asap. Please be patient while that's worked out.
That only fixes our regression tests, it doesn't help users who may still be using version 3.x. I also note that the logic in the pathscale.hpp is completely backwards - it should be something like: #if NAME <= VERSION1 // define defect macros for version 1 or less #define BOOST_NO_FOO1 #endif #if NAME <= VERSION2 // define defect macros for version 2 or less #define BOOST_NO_FOO2 #endif #if NAME >= VERSION1 // define optional feature macros for version 1 newer #define BOOST_HAS_FOO1 #endif #if NAME >= VERSION2 // define optional feature macros for version 2 newer #define BOOST_HAS_FOO2 #endif If pathscale is still a flavor of gcc then I agree we should probably revert this for this release, and fix properly for the next one.
