/*
   This is included *after* stdio, so the following is safe:

   CTex mixes output to stdio and stderr quite indiscriminately.
   This is a *bad thing*...

   Here I redefine stdout to be stderr, so that all output goes
   to the same stream (Web TeX's original terminal stream).  Having
   done this, I trap *all* I/O library calls, and filter out any
   for stderr, which I redirect into a RISC_OS window.  The ones
   which are not redirected are still intercepted to give the
   wimp polling loop a chance to do some work.
      This is also a convenient hook for trapping dvi writes to
   a file, in order to redirect them to a pipe - and then send the
   dvi straight to the dvi viewer which can start immediately.
      Finally, the editor to be invoked on error is my hack of
   uEmacs, which accepts a -line parameter, *and* multitasks under
   the wimp!
      ... this is turning into quite a nice little system... (TeXtures
   eat your heart out :-))
