Ilya, 

Techniclally this is a PROJ.4 issue and would be better
addressed on that mailing list. 

The problem is that you are including projects.h, the "private"
PROJ.4 include file.  If you include proj_api.h, the public 
interfaces, you will not run into this incompatibility with windows.h.

Best regards,
