The patch to tfformat.c is a separate issue unrelated to the performance
problem.  The problem is that including stdlib.h results in the inclusion of
stdio.h under hpux 10.20.  This causes conflicts with the defines in
libio/iolibio.h.

I am not totally happy with the patch to tfformat.c although it resolves
the problem.  Possibly, the exit at line 4067 should be changed to
`return 0' and the include of stdlib.h removed.

I agree about the performance problem.  This used to run ok.  There
have been a few other threads about c++ performance problems, so possibly
when they are resolved this will also be fixed.

The libio.exp patch did expose a problem with i686-pc-linux-gnu and tFile.
As of earlier today, this still wasn't fixed.  See
<http://gcc.gnu.org/ml/gcc-bugs/2000-09/msg00037.html>.
