Interface changes: - * change type for bool used in headers to NCURSES_BOOL, which - usually is the same as the compiler's definition for bool. - * add all but two functions for X/Open curses wide-character - support. These are only available if the library is configured - using the --enable-widec option.

This makes hds200 fit. - + modify tgetent() to check if exit_attribute_mode resets the - alternate character set, and if so, attempt to adjust the - copy of the termcap "me" string which it will return to - eliminate that part. In particular, 'screen' would lose track - of line-drawing characters. - + add check/fix to comp_parse.c to suppress warning about - missing acsc string.
