There was a problem in the VS project files in 224.1, some source file
that should be built only on Unix was included by mistak. Simply drop
the source file(s) that don't compile and see if that helps.

Note that the Visual Studio project files are generated during the
"make dist" stage, and they don't get any kind of automatic testing,
and are to be taken with a grain of salt.
