Hi,

I always use boost as static libraries. For a long time, I have been
used to define macro BOOST_THREAD_USE_LIB on windows when
cross-compiling from linux to windows with mingw.

I have now made a new cross-compiler conformant with pthread (the
previous one had only win32 api) but then boost does not build (with
threadapi=posix). It seems that not defining BOOST_THREAD_USE_LIB
helps.

I do not remember why I used to define BOOST_THREAD_USE_LIB a long
time ago and cannot find any help in the doc
(http://www.boost.org/doc/libs/1_64_0/doc/html/thread/build.html).

What is the meaning of BOOST_THREAD_USE_LIB?
