I merely picked down (some weeks ago) the sources at
  ftp://alpha.gnu.org/gnu/bison/bison-1.49a.tar.gz   (862 kB)
appiled some of my Mac patches, and then compiled them, without going into
details. I do use Flex myself, producing working MacOS pre-X code, though,
but I did some tweaks to the skeleton file.

Thus, the facts of my report may or may not be relevant to you.

This function returns a UNIX file descriptor number, thus is platform
dependent, and not in the ISO C standard. Same applies to isatty(). For
system(), ISO C allows it to nothing, which in fact my compiler does
(nothing). Thus, one will have to write ones own extensions (which I did
for the Hugs MacOS port).

Those things have probably been changed with MacOS X, but the point I want
to bring out is that for ISO C programming, one cannot assume such things.
