compat/mingw: Support a timeout in the poll emulation if no fds are given

Browse Source 
Our poll() emulation did not support the timeout argument. With this patch
we support it as long as poll() does not need to wait on file descriptors
as well because in this case the call just amounts to Sleep().

This is needed if the user sets help.autocorrect is set to a positive
value.
