gethostby{name,addr}_r

[Robert Christ <rchrist@u.washington.edu>]

Hello,
I've noticed a small problem on digital unix 4.0.  DU supplies the
functions gethostbyname_r and gethostbyaddr_r in libc but these
functions do not conform to the prototypes used in
libraries/libldap/util-int.c.  Configure finds the functions and
defines HAVE_GETHOSTBY{NAME,ADDR}_R which causes bad things to
happen.  I recompiled after undefining those constants and things are
working for me.

I don't have a patch since I'm not sure of the best way to have
configure work this out for itself.

I hope this is helpful for someone.
