fair nuf =)

let's see ... i haven't built libncurses, rather using the native install's:

% ls -al /usr/lib/*ncurses*
   -rw-r--r--  1 root wheel 304580 Mar 25 21:30 libncurses.5.4.dylib
   -rw-r--r--  1 root wheel 278948 Mar 20 15:10 libncurses.5.dylib
   lrwxr-xr-x  1 root wheel     20 Apr 30 12:10 libncurses.dylib ->
   libncurses.5.4.dylib

so, how do i tell if the widec patch has been applied?

reading the release notes @ <http://www.gnu.org/software/ncurses/ncurses.html>, 
i note:

   Announcing ncurses 5.4
   ...
   Interface changes:
   add the remaining functions for X/Open curses wide-character  support.
       pecho_wchar()
       slk_wset()
           These are only available if the library is configured using the
           --enable-widec option.

and checking

% nm /usr/lib/libncurses.5.4.dylib

   ...
   libncurses.5.4.dylib(lib_pecho_wchar.o):
   965e5a10 T _pecho_wchar
            U _prefresh
            U _wadd_wch
            U _wecho_wchar
            u dyld_stub_binding_helper

   libncurses.5.4.dylib(lib_slk_wset.o):
            U _SP
            U __DefaultRuneLocale
            U ___maskrune
            U __nc_doalloc
   a65d80a4 b _empty.0
            U _free
            U _isascii
            U _memset
   965e5a8c T _slk_wset
            U _sprintf
            U _strcpy
            U _wcrtomb
            U _wcslen
            U _wcswidth
            u dyld_stub_binding_helper
   ...

if i'm reading this correctly, the funcs ARE defined/available, so the lib WAS 
config'd with widec support.  true?

config'ing lynx2.8.6dev.11 w/ BOTH ip6 & widec options as:

   ./configure \
   --prefix=/usr/local \
   --with-ssl=/usr/local/ssl \
   --with-zlib \
   --with-screen=ncurses \
   --enable-color-style \
   --enable-default-colors \
   --enable-change-exec \
   --enable-cgi-links \
   --enable-exec-links \
   --enable-exec-scripts \
   --disable-nls \
   --enable-ipv6 \
   --enable-widec

with the 'temp changes' to netdb.h 'ON', i.e.:

=====================================
(EDITOR) /usr/include/netdb.h
   @115
        struct  hostent {
                char    *h_name;    /* official name of host */
                char    **h_aliases;    /* alias list */
                int h_addrtype; /* host address type */
                int h_length;   /* length of address */
                char    **h_addr_list;  /* list of addresses from name server */
   ---    #ifndef _POSIX_C_SOURCE
   	     #define h_addr  h_addr_list[0]  /* address, for backward compatiblity 
*/
   ---    #endif /* !_POSIX_C_SOURCE */
             };
=====================================


'make' & 'make install' complete OK.

checking:

% lynx -version
   Lynx Version 2.8.6dev.11 (05 Jan 2005)
   libwww-FM 2.14, SSL-MM 1.4.1, OpenSSL 0.9.7g, ncurses 5.4.20040208(wide)
   Built on darwin8.0.0 May  1 2005 15:36:05

and:

% otool -L /usr/local/bin/lynx
   /usr/local/bin/lynx:

           (compatibility version 1.0.0, current version 88.0.0)

seem to indicate that widec support is ON.

as for IP6 support, yes it compiles, but not sure how to test ...

hth,
