Wouldn't it be better to change the selection code to the following?
#elif defined(BOOST_HAS_WINTHREADS) # include <boost/detail/lwm_win32_cs.hpp> #else
This is (I suspect) not done to avoid the old issue with /Za defining BOOST_DISABLE_WIN32 defining BOOST_DISABLE_THREADS undefining BOOST_HAS_WINTHREADS. On the other hand, in this specific case /Za would lead to the (incorrect) selection of lwm_nop and the win32_cs branch would never be reached, so it would "work" (that is, fail in the same way). :-)
You can have both checks (the extra check for WIN32 et al. is immaterial to the cygwin/mingw case): #elif defined(BOOST_HAS_WINTHREADS) ||\ defined(WIN32) || defined(_WIN32) || defined(__WIN32__) # include <boost/detail/lwm_win32_cs.hpp> #else Joaquín M López Muñoz Telefónica, Investigación y Desarrollo
