in thread Read STDOUT from Win32::Job while process is running

Hmm ... maybe Inline::C should provide an option that allows one to place C code ahead of those inclusions. (TODO ?)

I wonder if, in this case, it wouldn't be possible to pass a -D_WIN32_WINNT=0x0500 to the compiler CCFLAGS?

After all, if CORE/win32.h did its job properly I think it would assign the actual value associated with the OS on which perl was running, not just provide a minimum supported value.

Agreed. But the whole (MS) concept of a define that you specify to say that you want at least version x.xxx, then preventing anything later than version x.xx being included, is a weird way to write header files.

As you say, the best solution to the problem that creates, would be for win32.h to define it to be "the current OS version" at compile time, but I can't find a ready source for that information amongst the MSC pre-defines.

    Yes - that works for this case. (I didn't think of doing that.)
    There are, I think, (hypothetical) situations where that approach would be found wanting - eg if the define depended upon what else is defined (#ifdef/#else/#endif), or if you need to include a header.

    I can't either - it may not exist. The only way I know of is GetOSVersion().

      That crossed my mind too, but there's no way to get at it in time for the pre-compiler stage.

      One possibility is the ver command:

      c:\test>ver

Microsoft Windows [Version 6.0.6001]

      but I can't see a way to use it.
