Maybe something like this ?

If instead of defining NOT_HAVE_INET_PTON_PROTO we defined
HAVE_INET_PTON_PROTO the check in curl/lib/inet_pton.h should be of
the following style.

#if defined(HAVE_INET_PTON) && !defined(HAVE_INET_PTON_PROTO)

Which would force the manual definition of HAVE_INET_PTON_PROTO for
all platforms that lack autoconf.

You can choose which option seems best.
