Hallo, I'd like to inform those of you that use Boost with Borland's BCB2006 product that I just released version 0.3 of bcbboost - the unofficial BCB Boost patches. This is a set of modified sources from Boost 1.33.1 that allow you to build and use some of the libraries from that release with the latest Borland compiler, bcc32 5.8.1 . Bcbboost is available from SourceForge: http://bcbboost.sourceforge.net/ This release contains improvements to date_time, call_traits, compressed_pair, math/octonion, numeric/conversion, optional, random and type_traits. Changes impact also graph, format and possibly other libraries. Many thanks to Alisdair Meredith: most of this release is a backport of the work he's done to add BCB2006 support to Boost's mainline.
