I don't have a RELENG_4 system around any more, but it sounds like
you're missing part of the source tree you should have.  Do you have
/usr/src/contrib/cvs/src/stack.c?  How did you do the update of your
sources?

No.  Remember to check /usr/src/UPDATING for more information before
starting an upgrade...
