Patch for solaris 2.x to provide nsswitch wins resolution

[Steven Tamm]

The configure.in script defines SUNOS5 if the host_os is solaris.  I wasn't
questioning whether or not the predefine was correct, I was questioning
whether it was appropriate, considering that in the configure.in
winbind_nss_solaris is included on HPUX.  So the wins.c solaris portion
probably also needs to include HPUX.

I don't know how the samba team is organized; but my assumption was that
whoever was dealing with winbind and nsswitch would know what to do with the
#ifdef, whether that would be place that code in a separate file called
"wins_solaris.c" or create another AC_DEFINE like "NSSWITCH_CONSTR_STYLE" or
something like that.

To get a full list of possibly-predefined symbols on
a particular installation of gcc, you can do something
like
  tr ' ' '\012' < /usr/lib/gcc-lib/i386-redhat-linux/3.2/specs | grep D
| sed 's/.*-D//' | sort -u

but it's better to do autoconf-style feature tests than
#if operatingsystem
style tests, isn't it?
