+ + modify rules in Ada95/src/Makefile.in to ensure that the PIC option
+ is not used when building a static library (report by Nicolas
+ Boulenguez):
+ + Ada95 build-fix for big-endian architectures such as sparc. This
+ undoes one of the fixes from 20110319, which added an "Unused" member
+ to representation clauses, replacing that with pragmas to suppress
+ warnings about unused bits (patch by Nicolas Boulenguez):

+ + add check in test/configure for use_window, use_screen.
+ + add configure-checks for getopt's variables, which may be declared
+ as different types on some Unix systems.
+ + add check in test/configure for some legacy curses types of the
+ function pointer passed to tputs().
+ + modify init_pair() to accept -1's for color value after
+ assume_default_colors() has been called (Debian #337905).
+ + modify test/background.c, adding commmand-line options to demonstrate
+ assume_default_colors() and use_default_colors().
+
+20110416
+ + modify configure script/source-code to only define _POSIX_SOURCE if
+ the checks for sigaction and/or termios fail, and if _POSIX_C_SOURCE
+ and _XOPEN_SOURCE are undefined (report by Valentin Ochs).
