Samba build failures on MacOS X

[Steve French]

FYI - Noticed current Samba master doesn't build on MacOS X

./configure --without-acl-support
make

Ended up with the readline compile failure:

[1978/3885] Compiling libcli/smbreadline/smbreadline.c

../libcli/smbreadline/smbreadline.c:139:38: error: use of undeclared
identifier 'CPPFunction'

                rl_attempted_completion_function = RL_COMPLETION_CAST
completion_fn;

                                                   ^

../lib/replace/system/readline.h:47:31: note: expanded from macro
'RL_COMPLETION_CAST'

#  define RL_COMPLETION_CAST (CPPFunction *)

                              ^

../libcli/smbreadline/smbreadline.c:139:38: error: expected expression

../lib/replace/system/readline.h:47:44: note: expanded from macro
'RL_COMPLETION_CAST'

#  define RL_COMPLETION_CAST (CPPFunction *)

That is easy enough to workaround by forcing the cast to rl_completion_func_t in

rl_attempted_completion_function = (rl_completion_func_t *)   completion_fn;

but the various problems with socket header definitions look harder to
work around
