I have checked the man pages on Linux, they claim that strdup(3) was
POSIX.1-2001, but strndup(3) a GNU extension:

...
CONFORMING TO
       strdup() conforms to SVr4, 4.3BSD, POSIX.1-2001.  strndup(),
       strdupa(), and strndupa() are  GNU extensions.

Any way, we must provide support for Solaris 10, because our customers
run these servers too.

There is https://www.gnu.org/software/gnulib/ and I will see if I could
use this.

Yep, at least cups-filter should probe for such exotic C-calls :-)
