Compiling a CGI-binary works fine. During compilation of the apache-module, I got the following warnings & errors:

php4apache.dll - 2 error(s), 6 warning(s)

I also get these warnings when I compile 4.1.0RC1 or 4.0.7RC3, but the fatal errors only show up with the latest CVS.

I'm using Visual C++ on Windows 2000.
