A few months back Matt D had mentioned the idea of compatibility.h, ahem,
portability.h
Then instead of adding quirks for various OS's we could require that
the platform provide the <portability.h> file according to the
standard <snip> portability.h would have things like:
#define _SPS_HAS_SENDFILE_A_ 1 /* type A sendfile */
#define _SPS_HAS_SENDFILE_B_ 1 /* type B sendfile */
#define _SPS_HAS_VSNPRINTF 1 /* vsnprintf supported */
Anymore thoughts on the idea?
