Created Issue: "TextualConventionMacro.Syntax == null" [7246]

The problem is a bug in "textualconvention_macro" of "Smi.g" file.
I found it fixed at discussion "http://sharpsnmplib.codeplex.com/discussions/361816"

but in current bigdipper_7.5_src.zip I downloaded on "2012/12/17", the "Smi.g" is still wrong.
TextualConventionMacro.Syntax always return null.

I attach a correct "Smi.g" got from "https://github.com/lextm/sharpsnmplib/commit/3cb1d12d1bf0027f0d19a66c51db0a962b53704a"

please check it, thanks!
