the mbuni patch

where do you read up/who to ask  on specifics of the patches ?

found a bit written about it...

"Mbuni really uses only two parts of Kannel: GWLIB and the WAP library. 
> GWLIB currently has to be patched, because of the way the cfg module 
> works (directives have to be compiled in). We also patch the makefile so 
> that WAP libs (and headers) are installed/exposed. One interim option 
> might be to fold the patch into Kannel.
"

but looking for specifics/reasons, so can help decide how to merge with my later version of kannel..

Thanks
