+ + improve cleanup() function in lib_tstp.c, using _exit() rather than
+ exit() and checking for SIGTERM rather than SIGQUIT (prompted by
+ comments forwarded by Nicholas Marriott).
+ + reduce name pollution from term.h, moving fallback #define's for
+ tcgetattr(), etc., to new private header nc_termios.h (report by
+ Sergio NNX).
+ + two minor fixes for tracing (patch by Vassili Courzakis).
+ + improve trace initialization by starting it in use_env() and
+ ripoffline().
+ + review old email, add details for some changelog entries.
+
+20110611
+ + update minix entry to minix 3.2 (Thomas Cort).

+
+20110604
+ + fixes for MirBSD port:
+ + set default prefix to /usr.
+ + add support for shared libraries in configure script.
+ + use S_ISREG and S_ISDIR consistently, with fallback definitions.
+ + add a few more checks based on ncurses/link_test.
+ + modify MKlib_gen.sh to handle sp-funcs renaming of NCURSES_OUTC type.
+
+20110528
+ + add case to CF_SHARED_OPTS for Interix (patch by Markus Duft).
+ + used ncurses/link_test to check for behavior when the terminal has
+ not been initialized and when an application passes null pointers
+ to the library. Added checks to cover this (prompted by Redhat
+ #707344).
+ + modify MKlib_gen.sh to make its main() function call each function
+ with zero parameters, to help find inconsistent checking for null
+ pointers, etc.
