GNU Go 3.1.24 released February 3, 2002

I left out the patch arend_1_24.3 because I gather the
purpose of that patch was more to solicit comment than
to be included in the CVS.

I included an ad hoc fix for the problem Marco reported,
namely the semeai code won't read to an arbitrary depth
any more. The game in question is included as
regression/games/semeai/infinity.sgf.

arend_1_24.4. DFA cleanup and more, promising a speedup. 
inge_1_24.1. Cleanup.
gunnar_1_24.3. AFFINE_TRANSFORM() macro. 
trevor_1_24.6. Spam stopper. 
trevor_1_24.4. Tuning. 
trevor_1_24.3. Various changes 
trevor_1_24.5. VC stuff. 
trevor_1_24.2. test and HTML view tweeks. 
brandsma_1_24.1. VC patch for mkpat.dsp. 
semeai_1_24.2. New semeai test and revision of update_status in semeai.c 
gunnar_1_24.2. Alternate connection reader. 
semeai_1_24.1b. Supercedes semeai_1_24.1a and includes arend_1_24.2. 
gunnar_1_24.1. Cleanup. 
trevor_1_23.4a. Experimental pattern-based tactical reading.
arend_1_24.1. Bugfix. 
trevor_1_24.1. Taking into account a recent change in gtp worm_stones.
