In one of the answers to this question jalf spoke about useful define NOMINMAX, that could prevent from unwanted defining min/max macros. Are there other useful defines that can help to control windows.h (or other Windows headers, for instance Microsoft C Runtime headers or STL implementation) behavior?

+5  A: 

There's WIN32_LEAN_AND_MEAN which causes some of the lesser used child headers to not be loaded.

This forum post has a decent discussion about that macro in particular.

The most commonly used is probably WIN32_LEAN_AND_MEAN - it disables rarely used parts of the API. You can find more on MSDN's Using the Windows Headers.

I remembered wrong about MSDN listing those defines, so here's list from windows.h:

/*  If defined, the following flags inhibit definition
 *     of the indicated items.
 *
 *  NOGDICAPMASKS     - CC_*, LC_*, PC_*, CP_*, TC_*, RC_

Link leads to the article which mention only WIN32_LEAN_AND_MEAN. Wrong link?
Kirill V. Lyadvinsky
Hm, I though it lists NOxxx defines. I'll edit my answer to include that list.
PiotrLegnica
The article also says to look in windows.h for more macros. ("For a list of support NOapi symbols, see Windows.h")I don't think there is any complete reference documentation.
jalf
Well, that comment is apparently the only one. I could swear I saw this on MSDN somewhere, though.

+2  A: 

MFC projects can use VC_EXTRALEAN since WIN32_LEAN_AND_MEAN is already defined by MFC. I also recommend enabling STRICT.
