GNU Go 3.1.4 released September 14, 2001

The CVS tag for this release is rel-3-1-4.

I've taken the gnugo-info files out of the distribution to save
space. Of course they're built automatically if you're running
GNU/Linux. Let me know if this causes problems for anyone.
They should go back in the stable releases.

I'd also like to split the regressions into a separate
tarball but haven't done that yet.

The following patches were used:

atarifix_1_4.2. Fixes a bug in atari_1_4.2
gunnar_1_4.3. Comments on Indigo 9x9 game and one bugfix.
gunnar_1_4.2. Minor bugfix. 
movenum_0_1.1. Move numbers were printed wrong in ascii mode.
gunnar_1_4.1. Bugfix and showtime cleanup. 
getopt_1_4.1. Use gg_getopt_long. 
free_1_4.1. Recursively frees SGF trees.
atari_1_4.2. Atari atari revisions. 

The patch backspace_1_4.1 is still pending. I'd like to hear from Wolfgang or
someone using Cygwin whether this fixes the bug or not.

The patch teun_1_4.1 was rejected since it conflicts with Gunnar's 1D scheme.

The patch inge_1_3.1 was backed out because it broke twogtp. Because
it promised a really substantial speedup under some circumstances,
this patch may be worth fixing.
