Is there any way I can tell if my code is being compiled with cl.exe?

This has probably been asked before, but I couldn't find it.

Is there a way to determine, at compile time, if my code is being compiled by cl.exe?

I will be using this to conditionally include (during prepr开发者_运维百科ocessing, via #ifdef) certain #pragma directives only supported by cl.exe.

If you want to make decisions on the cl.exe version, use _MSC_BUILD.

However, first check for _MSC_VER, because _MSC_BUILD was not available in VS 2005.

I think you can check for the _MSC_BUILD macro.
