Re the /MT flag, I can't say now because I don't really know.

Since you wan't to build the library yourself, you should get the source 
via anonymous CVS (see the web page for details - 
http://sources.redhat.com/pthreads-win32/). It has the latest bug fixes, 
and currently bug fixes are the only changes from the latest versions 
available from ftp. I will update the ftp versions ASAP.

See the FAQ file, answer to Q2. For VC you don't need to do anything 
because it is the default. The others can be used if you add the 
appropriate compile flags when you build your application code, and when 
you build the library if you don't use the prebuilt dlls.
