Quick fix for krb5 & errno conflict

This file contains two small scripts which "fix" the krb5 code so that it can
be compiled with the newest glibc (~x86).  The scripts replace "extern int
errno" with "include <errno.h>" at the file level, and removes any "extern int
errno" declarations inside functions. 

This is *not* a patch, but it could probably be used to create one fairly
easily.

Applied the fix. Now it builds just fine. 
 
I didn't bump the revision since people that have already built it obviously don't need to build it 
again. 

*** Bug 17691 has been marked as a duplicate of this bug. ***

actually, people *do* need to rebuild the package ...

the old version will refer to an external integer and when they update their glibc,
their krb will be broken

Ok, bumped to -r1 
 

Should be fixed now.
