A developer does not have to track compiler/library releases. Boost.Config
macros take care of tracking, backed up by the regression testers.

Also Compilers are starting to support the C++ committee's Standing
Document 6. See
http://isocpp.org/std/standing-documents/sd-6-sg10-feature-test-recommendations
and that should help Boost.config track who is supporting what.
