+ add a check in start_color() to limit color-pairs to 256 when extended colors are not supported (patch by David Benjamin). + modify setcchar to omit no-longer-needed OR'ing of color pair in the SetAttr() macro (patch by David Benjamin). + add kich1 to sun terminfo entry (Yuri Pankov) + use bold rather than reverse for smso in sun-color terminfo entry (Yuri Pankov). + improve generation of termcap using tic/infocmp -C option, e.g., to correspond with 4.2BSD (prompted by discussion with Yuri Pankov regarding Schilling's test program): + translate %02 and %03 to %2 and %3 respectively. + suppress string capabilities which use %s, not supported by tgoto + use \040 rather than \s + expand null characters as \200 rather than \0 + modify configure script to support shared libraries for DragonFlyBSD.
