I've enclosed two patches.  The first affects Solaris compilability.  The
bug stems from netdb.h (where MAXHOSTNAMELEN is defined on a stock
system).  If the user has installed the header files from BIND 4.9.x,
there will be no definition of MAXHOSTNAMELEN.  The patch will, if all
else fails, try to include <arpa/nameser.h> and set MAXHOSTNAMELEN to
MAXDNAME, which is 256 (just like MAXHOSTNAMELEN on a stock system).

The second patch adds aliases for "ISNULL" to "IS NULL" and likewise for
"NOTNULL" to "IS NOT NULL".  I have not removed the postgres specific
ISNULL and NOTNULL.  I noticed this on the TODO list, and figured it would
be easy to remove.

The full semantics are:
        [ expression IS NULL ]
        [ expression IS NOT NULL ]
