Created attachment 8779 [details]
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.

[Comment 4 Wout Mertens (RETIRED) 2003-03-17 06:24:40 UTC]

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.

[Comment 6 SpanKY 2003-03-21 11:57:03 UTC]

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

[Comment 7 Wout Mertens (RETIRED) 2003-03-21 12:07:38 UTC]

Ok, bumped to -r1 
 

[Comment 8 Wout Mertens (RETIRED) 2003-03-21 12:08:08 UTC]

Should be fixed now.
