edit: more specific, discussion of *snprintf removed. See
the WIN32 macro seems to have meant different things at different times and to different developers. It should be reviewed to really mean the platform in general (or otherwise be given a clear definition and purpose), and compiler-specific macros should probably replace it in some cases. This overlaps with issue #94.
I consider MSVC source-level support somewhat low priority: mingw/msys are better than they were there is no build support for msvc anyway * there are close to zero users compiling asss with msvc
