preprocessor-definitions

I often see __WIN32, WIN32 or __WIN32__. I assume that this depends on the used preprocessor (either one from visual studio, or gcc etc).

Do I now have to check first for os and then for the used compiler? We are using here G++ 4.4.x, Visual Studio 2008 and Xcode (which I assume is a gcc again) and ATM we are using just __WIN32__, __APPLE__ and __LINUX__.

Asciidoc image inline macro vs. image block macro

as seen on Stack Overflow - Search for 'Stack Overflow'
I don't understand in which context an image block macro would be preferable to an image inline macro. I played around with a little test document and the only difference I could see is that I could "inline" (who would have guessed ;-)) the inline macro. So why not always use the inline version? >>> More
