- When defined to 1, the select backend will assume that select
- doesn't understand file descriptors but wants osf handles on
- win32 (this is the case when the select to be used is the winsock
- select). This means that it will call _get_osfhandle on the fd to
- convert it to an OS handle. Should not be defined on non-win32
- platforms.
