I don't know; POSIX says both sys/socket.h and netdb.h should declare
socklen_t, I was thinking of the case where a system doesn't have
sys/socket.h but has netdb.h.  Do you think we should only test for it
in sys/types.h + sys/socket.h?

There is a problem, of course, if it _is_ defined in netdb.h and the
application include that header file, but the test does not look
there.  Then there will be a type conflict.

Perhaps the M4 macro should create a socklen.h that include the proper
header files that is required to get the socklen_t type?  That would
be the most flexible, I think.  But it has the disadvantage that
applications need to include socklen.h, instead of simply using
socklen_t directly without worrying.
