in_addr_t is not defined on SunOS4...

[Alexandre Oliva <oliva@dcc.unicamp.br>]

... and inet_addr was assumed to return such a type.  I've hacked it
to explicitly use the return type of inet_addr (__typeof) to
initialize laddr, because I'm not sure in_addr_t is supposed to be
defined in sys/types.h on all platforms in which it would be useful.
Does anybody have an authoritative information?

Here's the patch.  Installed in branch and mainline.  (SunOS4 is
almost getting there!)

from  Alexandre Oliva  <oliva@dcc.unicamp.br>
	* java/net/natInetAddress.cc (aton, HAVE_INET_ADDR): Typedef
	in_addr_t to the return type of inet_addr, just in case it is not
	defined.
