This week we upgraded our VisualAge compiler from 6.0.0.8 to 6.0.0.13 (because of problems with the preprocessor) which is the latest PTF (which is ibm speak for 'service pack'). We will thus also use this updated version to run the regression tests during the weekend (which are reported here: http://tinyurl.com/bms8v). However we will have *many* regressions because of compilation problems in some headers that are (indirectly) used in many places. For instance one problem is the gcc_3_2_wknd struct in mpl/has_xxx.hpp (see attached compiler error report). I fiddled around a bit with it and I do not understand why the compiler reports gcc_3_2_wknd to be an incomplete class. I also noted that defining gcc_3_2_wknd outside of the trait struct works. But this solution is also problematic from the moment the BOOST_MPL_HAS_XX_TRAIT_NAMED_DEF is used twice in which case the gcc_3_2_wknd will be defined twice ;-( Any suggestions are welcome! warning: Python location is not configured warning: the Boost.Python library won't be built Building Boost.Regex with the optional Unicode/ICU support disabled.
