+ modify nc_tparm.h, adding guards against repeated inclusion, and
allowing TPARM_ARG to be overridden.
+ fix some strict compiler warnings in ncurses library.
+ correct limit-check in wredrawln, accounting for begy/begx values
(patch by David Benjamin).
+ fix most compiler warnings from clang.
+ amend build-fix for OpenSolaris, to ensure that a system header is
included in curses.h before testing feature symbols, since they
may be defined by that route.
+ for term-driver configuration, ensure that the driver pointer is
initialized in setupterm so that terminfo/termcap programs work.
+ amend fix for Debian #542031 to ensure that wattrset() returns only
OK or ERR, rather than the attribute value (report by Miroslav
Lichvar).
+ reorder WINDOWLIST to put WINDOW data after SCREEN pointer, making
_nc_screen_of() compatible between normal/wide libraries again (patch
by Miroslav Lichvar)
+ review/fix include-dependencies in modules files (report by Miroslav
Lichvar).
+ add configure option --enable-weak-symbols to turn on new feature.
+ add configure-check for availability of weak symbols.
+ modify linkage with pthread library to use weak symbols so that
applications not linked to that library will not use the mutexes,
etc. This relies on gcc, and may be platform-specific (patch by Dr
Werner Fink).
+ add note to INSTALL to document limitation of renaming of tic library
using the --with-ticlib configure option (report by Dr Werner Fink).
+ document (in manpage) why tputs does not detect I/O errors (prompted
by comments by Samuel Thibault).
+ fix remaining warnings from Klocwork report.
