The following errors are encountered when running boost regression tests on msvc with stdcxx-4.2.0. {{{ d:\boost\boost\boost\thread\win32\thread_primitives.hpp(184) : error C2065: 'NULL' : undeclared identifier d:\boost\boost\boost\thread\win32\thread_primitives.hpp(184) : error C2065: 'NULL' : undeclared identifier }}} I propose to add #include in thread_primitives.hpp to define the NULL macro, or even better - replace the all NULL macros to 0."
