With Visual Studio 2010 you get the warning.

...\tsrm\readdir.h(10): warning C4005: '_WIN32_WINNT' : macro redefinition
          C:\Programme\Microsoft SDKs\Windows\v7.0A\include\sdkddkver.h(197) : see previous definition of '_WIN32_WINNT'

Changing in readdir.h

#define _WIN32_WINNT 0x0400


#ifndef _WIN32_WINNT
#define _WIN32_WINNT 0x0400

would solve the problem.

Is it not fixed already in 5.3?

I speak about 5.2.x and in 5.2.14RC2 it is still not fixed.

Let me rephrase: 5.2 supports only VC6.

That means you can try with 5.3 (which should be fixed).

There was never a problem compiling php extensions with VS2003 and VS2005 and php version < 5.3.
For PHP we use the supplied binaries.

Why is it so difficult to made the proposed change.
This can be done in less than one minute.
Just for the upcoming 5.2.14 version.

5.2 never worked with recent compilers. We do not support them either.

5.3 supports both VC6 and more recent compilers (we use VC9 and test with VC10). Next major version will support only one (be 5.3 or 6.0).

5.2.14 is in RC phase (last one) and only very critical changes can be applied.

I wonder, why there's a bug reporting system, if you don't care for the bugs,
even if the bug can easily be fixed like this one.
 [2010-07-13 10:38 UTC]
What are you talking about? You ask something that we can't fix at this stage. I don't think it is so hard to understand (last RC and only critical fixes go to 5.2 from now on). We also always claimed, advertised and documented that the only compiler we support for 5.2 is VC6.

Now, about windows and php, if you are serious about that, then I strongly suggest you to move to 5.3. Windows support is much better with 5.3, regular updates for the libraries, better portability, faster, more stable. And it supports modern VC versions.
