  Portability problems fixed by Gnulib:
  @itemize
  @item
  Some platforms start the child with closed stdin or stdout if the
  standard descriptors were closed in the parent:
  Cygwin 1.5.x.
  @end itemize
  
  Portability problems not fixed by Gnulib:
  @itemize
  @item
  Some platforms mistakenly set the close-on-exec bit, then if it is
  cleared by the application, the platform then leaks file descriptors
  from earlier @code{popen} calls into subsequent @code{popen} children:
  Cygwin 1.5.x.
  @end itemize
