Following are 2 patches for kerberos 1.4.1 to build on AIX 5.2. The
patches are for the problem of not being able to resolve the address for
the kdc.
The #ifndef LANL and #ifdef LANL are locale compiler directives and will
need to be changed or specifiy -D LANL in configure process.
The patch for dsnglue.c is if "thread-support" is enabled. The patch adds
a 1024 byte buffer after the _res_state structure. IBM AIX has a problem
where 735+- bytes are overlaid when res_ninit is called. The 1024 bytes
pads the storage to stop res_ninit from overlaying critical storage. Ken
Raeburn had tried a similar patch with 72 bytes.

The patch for locate_kdc.c is when "disable-thread-support" is set for
configure. Again the #ifndef LANL and #ifdef LANL is a local compiler
directive. This will need to be changed for local setting or -D LANL set
for configure process.
