So fd_is_pipe returns zero either way, but something about calling
PeekNamedPipe on a non-pipe disturbs what happens later, you're saying.

How did it get into WaitForMultipleObjects?  Did isatty return true -
in which case it shouldn't have called fd_is_pipe?  Otherwise, see the
call site, where no handle is provided.  So we must be falling back to
the file handle (mingw-hdep.c).  Maybe we need to do something
different to simulate select on a file.
