Re: Attempting new dissectors using ASN and asn2wrs under MSVC 2008E

Thanks, Anders.  Both suggestions helped.

Turns out that's not the only ASN construct in the SLE specs that 
asn2wrs doesn't like, so I'll be making a list of them as I progress.

BTW - this did need to be added to the output of asn2wrs, which supposedly 
shouldn't be modified, and I'd have expected it to be in the generated 
file.  Is it enough to mention that here, or should it be entered in 
bugzilla also?
