No, there isn't.

Same goes for NetBSD and OpenBSD. Someone obviously confuses FreeBSD 
with BSD there. But hey, that's still better than confusing "portable" 
with "should compile on all Linux distros". :)

A saner way would be to replace those "#ifdef BSD" with "#ifdef 
SO_NOSIGPIPE" in order to check if the system allows turning off SIGPIPE 
for a socket. This is how for example BIND does it.

Try that.
