POSIX specification:@* @url{http://www.opengroup.org/onlinepubs/9699919799/functions/sleep.html}

Gnulib module: sleep

Portability problems fixed by Gnulib:
@itemize
@item
This function is missing on some platforms:
mingw (2005 or newer).
@item
This function takes milliseconds as argument and returns @code{void} on some
platforms:
mingw (2005 and older).
@item
This function cannot sleep longer than 49.7 days on some platforms:
Cygwin 1.5.x.
@end itemize

Portability problems not fixed by Gnulib:
@itemize
@item
According to POSIX, the @code{sleep} function may interfere with the program's
use of the @code{SIGALRM} signal.  On Linux, it doesn't; on other platforms,
it may.
