Oh bugger, you really are immune to reason...

1. This is not the only macro.
2. A library project wanting to distribute a similar file has to do a lot of work to adapt it to its own requirements.
3. It is a maintenance nightmare, because e.g. _MSC_VER is combined from the major and minor version number of the compiler, so for VS 2010 it is 1600. This requires that for every new version you'll be adding a new branch in the #if ... #elif ... #endif maze, translating that number into a readable name. Now, imagine other compilers starting to adopt this "magic", this file would just explode (and compilation would probably slow down to a crawl).

This is really wearing my patience right now. I suggest we stop this absolutely futile discussion and let Olaf come up with something constructive for once (such as a patch). At least I will.
