I've reconfigured ncurses with --disable-leaks and recompiled,
and added a call to _nc_free_and_exit() at the end of nano,
but the compiler says it does not known the function: implicit
declaration.  Do I need to use still other configure flags?
I've used this:

  ./configure -C --enable-widec --with-shared --prefix=/usr/local 
--disable-leaks


By the way, while compiling ncurses, I saw this warning pass:

../test/picsmap.c: In function ‘lookup_rgb’:
../test/picsmap.c:965:11: warning: implicit declaration of function ‘strcasecmp’
[-Wimplicit-function-declaration]
      if (!strcasecmp(name, rgb_table[n].name)) {
           ^~~~~~~~~~


Also, after installation of ncurses into /usr/local, there
seems to be something wrong with one of the header files:

In file included from ./nano.h:89:
In file included from /usr/include/ncursesw/curses.h:2076:
/usr/local/include/ncursesw/unctrl.h:61:54: error: conflicting types for 
'unctrl'
NCURSES_EXPORT(NCURSES_CONST char *) NCURSES_SP_NAME(unctrl) (SCREEN*, chtype);
                                                     ^
/usr/local/include/ncursesw/unctrl.h:58:38: note: previous declaration is here
NCURSES_EXPORT(NCURSES_CONST char *) unctrl (chtype);

I work around that by editing that header file and changing the "#if 1"
on line 60 to "#if 0".
