That did it.  It's a little curious that sys/socket.h doesn't mention
that anywhere though.

I see a couple of places where configure neglects to include sys/types
before sys/socket.  Fixing now.

Because it shouldn't be so.  Can you look in config.log what the real
reason of the failure was?  Maybe it's a bug in FreeBSD.

It's been true for years that <sys/socket.h> requires <sys/types.h> on
some platforms.  How do you think I knew what to recommend?  There's
no point in arguing about it, it's just a fact.

            regards, tom lane

The man page for socket on Linux says you need both, but you can get away
without it.

It's easy enough to test if a platform does the sane thing:

[andrew@Thor andrew]$ echo '#include <sys/socket.h>' > blurfl.c
[andrew@Thor andrew]$ gcc -E -M blurfl.c
blurfl.o: blurfl.c /usr/include/sys/socket.h /usr/include/features.h \
  /usr/include/sys/cdefs.h /usr/include/gnu/stubs.h \
  /usr/include/sys/uio.h /usr/include/sys/types.h \
[snip]

Probably the best bet is just include sys/types.h just before any place
sys/socket.h is included, no? Should be harmless enough.

cheers

Sure, but it still may be a bug in FreeBSD if they don't document it and
if they pretend to follow standards, which they do.
