[omniORB] IPv6 configuration option

[Anthony Mallet]

Hello list,

I found useful to have an option to *disable* ipv6 support, even if it's
available in the system, for two reasons:

First, ipv6 might me available in the headers but disabled in the os
configuration.
Second, omniORB may have to interopere with ORBs that are not IPv6 aware,
even on ipv6-aware system.

I attach two patches that implement a --with-ipv6 configure
option. Option defaults to 'yes'. Patches have been done against
4.1.0beta2 public release. They have been commited to pkgsrc-wip
(http://pkgsrc-wip.sf.net) but it would be great if they could be
integrated in official realeases.

Thanks,
-- Anthony Mallet
