That's correct. long is always 32bit on windows.

Something on our TODO is to use fixed and portable size types like what we can find in stdint. I have put a windows version in win32/php_stdint.h if you are interested. Ideally we should do that for all platforms and make them available for all parts of php (extensions, engine or main).
