I would ack the patch except for the added extern statements.  I thought
extern was for functions and variables that are declared in another file.

I've been fixing the "no previous prototype" warnings in two ways:
1. declare the function static if it is only used in that file
2. Add a prototype in a header that is included in the file where the
function is defined and the file where it's used.

Thanks,
Myles
