Making krb5.h C++ friendly

["Zeqing (Fred) Xia" <fxia@juniper.net>]

Hi,

In my build environment krb5.h header cannot compile with g++ (3.4.5).
I did put krb5.h in extern "C" {..} bracket. 

I made the following changes to work around the problem. Of course my
program is limited in its usage of krb5 structures and functions. The
work-around probably will fail for some other programs. But I wonder
if anyone have similar issues and if it is appropriate to make krb5.h
itself more friendly to a c++ compiler.

Thanks.



Fred
