+ + modify configure script and makefiles in c++ and progs to allow the
+ directory used for rpath option to be overridden, e.g., to work
+ around updates to the variables used by tic during an install.
+ + add -K option to tic/infocmp, to provide stricter BSD-compatibility
+ for termcap output.
+ + add _nc_strict_bsd variable in tic library which controls the
+ "strict" BSD termcap compatibility from 20110723, plus these
+ features:
+ + allow escapes such as "\8" and "\9" when reading termcap
+ + disallow "\a", "\e", "\l", "\s" and "\:" escapes when reading
+ termcap files, passing through "a", "e", etc.
+ + expand "\:" as "\072" on output.
+ + modify _nc_get_token() to reset the token's string value in case
+ there is a string-typed token lacking the "=" marker.
+ + fix a few memory leaks in _nc_tgetent.
+ + fix a few places where reading from a termcap file could refer to
+ freed memory.
+ + add an overflow check when converting terminfo/termcap numeric
+ values, since terminfo stores those in a short, and they must be
+ positive.
+ + correct internal variables used for translating to termcap "%>"
+ feature, and translating from termcap %B to terminfo, needed by
+ tctest (cf: 19991211).
+ + amend a minor fix to acsc when loading a termcap file to separate it
+ from warnings needed for tic (cf: 20040710)
+ + modify logic in _nc_read_entry() and _nc_read_tic_entry() to allow
+ a termcap file to be handled via TERMINFO_DIRS.
+ + modify _nc_infotocap() to include non-mandatory padding when
+ translating to termcap.
+ + modify _nc_read_termcap_entry(), passing a flag in the case where
+ getcap is used, to reduce interactive warning messages.
