Yeah,  I read that as well, but I don't know of a way around it right 
now (I'm not a C hacker).

Here is the error I get if I fail to define __BSD_VISIBLE:

(cd .libs && rm -f libmutils.la && ln -s ../libmutils.la libmutils.la)
/usr/local/bin/bash ../../libtool --mode=compile --tag=CC gcc 
-DHAVE_CONFIG_H -I. -I. -I../..

In file included from stream.mx:265:
/usr/include/netinet/ip.h:49: error: syntax error before "u_int"
/usr/include/netinet/ip.h:148: error: syntax error before "u_char"
/usr/include/netinet/ip.h:200: error: syntax error before "u_char"

The problem is that netinet/ip.h looks like this:

struct ip {
         u_int   ip_hl:4,                /* header length */
                 ip_v:4;                 /* version */
         u_int   ip_v:4,                 /* version */
                 ip_hl:4;                /* header length */
         u_char  ip_tos;                 /* type of service */
         u_short ip_len;                 /* total length */

if I set __BSD_VISIBLE then u_int, u_char are typedef'd (in 
sys/types.h), otherwise they are not.

There is probably a better way, I just don't know what it is.
