Gnulib module: stdio, nonblocking

Portability problems fixed by Gnulib module @code{stdio}, together with module @code{nonblocking}:
@itemize
@item
When reading from a non-blocking pipe whose buffer is empty, this function
fails with @code{errno} being set to @code{EINVAL} instead of @code{EAGAIN} on
some platforms:
mingw, MSVC 9.
@end itemize

Portability problems not fixed by Gnulib:
@itemize
@item
On Windows platforms (excluding Cygwin), this function does not set @code{errno}
upon failure.
@end itemize
