+ fix case where progs/tput is used while sp-funcs is configure; this
requires save/restore of out-character function from _nc_prescreen
rather than the SCREEN structure (report by Charles Wilson).
+ fix typo in man/curs_trace.3x which caused incorrect symbolic links
+ improved configure macros CF_GCC_ATTRIBUTES, CF_PROG_LINT.
+ updated man/curs_trace.3x
+ limit hashing for termcap-names to 2-characters (Ubuntu #481740).
+ change a variable name in lib_newwin.c to make it clearer which
value is being freed on error (patch by Nicholas Marriott).
+ change internal return codes of _nc_wgetch() to check for cases
where KEY_CODE_YES should be returned, e.g., if a KEY_RESIZE was
ungetch'd, and read by wget_wch().
+ fix static-library build broken in 20070217 changes to remove "-ldl"
(report by Miroslav Lichvar).
+ change makefile/scripts for cygwin to allow building termlib.
+ use Form_Hook in manpages to match form.h
+ use Menu_Hook in manpages, as well as a few places in menu.h
+ correct form- and menu-manpages to use specific Field_Options,
Menu_Options and Item_Options types.
+ correct prototype for _tracechar() in manpage (cf: 20011229).
+ correct prototype for wunctrl() in manpage.
