Subject: [PATCH] Add OICQ dissector
To: ethereal-dev@xxxxxxxxxxxx

 Hi list,

I write a dessector for OICQ,which is a popular IM software in China with over 15 millions users.

I hope it will be added in the next version.

This attachment  is source file.

Because when I sent Makefile.common.diff,Symantec AVF rejects my email :(

So I put diff files here.
