It is my understanding that you don't need to specify
BOOST_FILESYSTEM_VERSION when building Boost 1.44. This macro is to be
placed in the preprocessor settings of a program that uses Boost 1.44.

I upgraded to Boost 1.44 yesterday and was confused with this. I read
the following text from the source file
boost_1_44_0\libs\filesystem\v3\src\path.cpp which cleared up my
confusion:

// During the transition to V3, libraries are compiled with both V2
and V3 sources.
// On old compilers that don't support V3 anyhow, we just skip
everything so the compile
// will succeed and the library can be built.
