i try to compile the *.cpp files of boost::filesystem within the following environment:

os: Windows XP compiler: Visual C++ Toolkit 2003 (this is the free version of MS Visual C++ V7.1) boost: Version 1.31.0

If BOOST_WINDOWS is defined, the file windows.h is included in the sources: * exception.cpp * operations_posix_windows.cpp.

Otherwise the file errno.h is included.

BOOST_WINDOWS is defined within the environment mentioned above, but the compiler does not have a windows.h include file. Hence compilation fails. <snip>

You need to install the Windows Platform SDK as well as the Toolkit.
