Build on HP/UX

[Gary Williams <Gary.Williams@sas.com>]

When I try to build on HP/UX version 10.20, I get an error in util-int.c.
It seems to depend on the existence of h_errno, which on HP, you have to
define _X_OPEN_SOURCE_EXTENDED to get it defined.  Is anyone else successfully
building on HP with the current dev sources?

gcc -g -I../../include -I../../include -I/u/sasgwi/include -c  -fPIC -DPIC util-int.c -o .libs/util-int.lo
util-int.c: In function `ldap_pvt_gethostbyname_a':

util-int.c:174: for each function it appears in.)
