Hmm currently I'm using _vscprintf / vsprintf on Windows/MSVC inside #ifdef _WIN32 and vasprintf Ubuntu/gcc inside #else But my C-fu is to puny to figure out what #ifdefs to use to detect what combination of C compiler and libc I'm compiling under. Apparently it's important with snprintf since some implementations return "an unspecified return value less than 1" with size=0. I don't want to have to use autoconf or swtich to a gcc on Windows.
