-Added optional DISABLE_NT_SUPPORT to not compile NT specific code 

-Not NT systems set C:\ as the profile directory.  This should be changed to
 the basedir most likely...
-Defined INVALID_SET_FILE_POINTER for systems that don't have the latest
 platform SDK.  According to MSDN doc, this should be okay.
