Welcome to the Pthread replacement DNS system for PGPlus.

Normally this paragraph contains all the licence mumbo jumbo,
however as I can't release this under the GPL and remain fully
compatable with the PGPlus licence, this code is therefore to
be considered to inherit the same licence as the PGPlus
version your installing into.

Please note this system uses Pthreads to overcome the problem
of a slow lookup holding up potentially quicker lookups. Most
linux distributions ship with the required library, however
some may not. The easiest way to check is to compile the server,
and if it doesn't report any errors then move on to modifying
the talker files. If it does report problems then you need
to bug your system administrator to install the Pthread library's.

This code has been tested only against PG+1.0.11, from memory I
can't think of any reason why it shouldn't install into a 
1.0.10 or 1.0.9 or earlier version, however I can't think of
any valid reasons why your not using the latest version, so if
it foobars an earlier version tough!

Notes and credits:

init_pthread_server() is based very much on init_ident_server() from
the ident distribution, so credit where its due.

Thanks to comp.programming.threads who critiqued the first version
of the code.

Stratocaster@Downtown who tested the installation notes and spotted 
my slight ommission.
