Make some more fixes

This change deletes mkfifo() so that GNU Make on Windows will work in
parallel mode using its pipe-based implementation. There's an example
called greenbean2 now, which shows how to build a scalable web server
for Windows with 10k+ threads. The accuracy of clock_nanosleep is now
significantly improved on Linux.
