Comment 3 Ulrich Drepper 2007-10-06 17:02:41 UTC 
This comment is not complete.  There are other reasons.  For instance, nested
functions must be inlined in many cases to avoid executable stacks.
Comment 4 Andreas Jaeger 2007-10-28 05:25:17 UTC 
patch checked into glibc head.

Comment 6 Carlos O'Donell 2008-02-08 14:01:42 UTC 
It doesn't look like this was ever checked into glibc head?

I've updated the patch to include Ulrich's comments about nested functions.

OK to checkin?
