AFAICT, the proposed patch will break things on at least some versions
of HPUX. You can't just arbitrarily remove the reference to -lxnet,
at least not without explaining to us why the existing comment about it
is wrong. Likewise, removing -D_XOPEN_SOURCE_EXTENDED isn't
acceptable without a whole more supporting evidence than you've
provided. (I'm fairly certain that the latter will break the build on
my old HPUX 10.20 box, for example.)
