Yes, sure. Well spotted. The flag that you need is __EXTENSIONS__, and
- surprise surprise - it is enabled by gnulib's 'extensions' module.
This is what was missing:
2008-04-29 Bruno Haible <[EMAIL PROTECTED]>
* m4/inet_ntop.m4 (gl_INET_NTOP): Require gl_USE_SYSTEM_EXTENSIONS.
* m4/inet_pton.m4 (gl_INET_PTON): Likewise.
* modules/inet_ntop (Depends-on): Add extensions.
* modules/inet_pton (Depends-on): Likewise.
