problems compiling H.323 ASN.1

Hi Vance,

Did you get an answer to this? I believe that constraints are not
implemented yet, removing them has no effect on the protocol exchanges (its
just validation for what you can put into them).

By the way, H.323 is ASN.1 PER so you need:

1>asn1ct:compile("H323-MESSAGES.asn", [per]).

or it will default to ASN.1 BER.

(if you knew this already I apologise)

I've lost all my files. Grrr. But I'm interested enough to get all the
H.323v4 files and compile them. Almost there :-)

/Bruce
