Test 8,10 and 23 fails with the following output. (Test23 works ok in
a window with 24 rows.) Compiling without optimization, as someone
suggested in gnu.g++.lib.bug, doesn't change anything.

About test8:

There was a typo in a preliminary version of libg++-1.34.0
src/BitSet.cc:longtoBitSet that caused it to fail on `big-endian'
machines, and that you might have if you ftp'ed it from rocky. The
correct version is:

BitSetTmp longtoBitSet(unsigned long w)
{
  unsigned short u[2];
  u[0] = w & ((unsigned short)(~(0)));
  u[1] = w >> BITSETBITS;
  BitSetRep* r = BitSetalloc(0, &u[0], 2, 0, 3);
  trim(r);
  return r;
}

If this is not your problem, try compiling *without* the -fsave-memoized
option, which is buggy in g++-1.34.1

About test10:

As was previously posted, you must, on a sun3, compile src/RNG.cc with
the -ffloat-store option.

About test23:

No one has been able to tell me how/why this sometimes fails on Sun3s
and Sun4s. The test program does require running on a screen of at
least 24X80, but it seems that it sometimes fails in calling
libcurses:subwin even in such cases, but never when run from a remote
terminal. Any further diagnosis (e.g., a gdb run after compiling your
local libcurses library -g) would be very much apreciated.
