*grin* The maybe_set_rd_gen function and associated code was removed in
1999 when Jeff introduced lcm.c (ChangeLog.1).
Note that rd_gen and friends are only used for classic GCSE (not LCM
based) which only is used when optimize_size. But in that case it indeed
doesn't do much ;) And noone noticed. An argument for ripping out the
classic GCSE stuff without second thought.
Ciao,
Michael.
