Comment:

 The checks on $host_os in aclocal.m4 are from libtool, which sadly is
 closely coupled to details of different OSes and compilers (probably by
 necessity, or at least practicality), and because of that sometimes needs
 updating for new major OS and compiler releases.

 The ideal for configure tests is not to key off the OS or version numbers
 but to test features instead.  Other platforms besides Solaris may also
 need -lxnet, and it's possible some versions of Solaris may not
 (particular future versions) so it's more robust to just check if
 socketpair() is found with no extra libraries and if not to retry with
 -lxnet, regardless of the current value of $host_os.

 Richard's suggestion looks good, so I've gone with that, and committed to
 trunk as r13580.  I tested 13582 configures and builds on Solaris with
 socketpair enabled.

 Marking for backporting for 1.0.17.
