The original patch had documentation.  You should not make patches worse 
in the course of reworking or updating them; documentation is required for 
all patches with user-visible features.  The original also had ChangeLog 
entries following the usual conventions; please make sure to follow the 
style of existing entries.

Since I previously approved the C changes in 
<http://gcc.gnu.org/ml/gcc-patches/2009-10/msg00562.html>, and do not wish 
to duplicate review effort, I am not inclined to review any reworked patch 
without adequate explanation of what was changed from the approved version 
and why it needed to be changed.  The initial basis should be to make only 
those changes to the approved patch that are strictly necessary to update 
it to newer sources or to fix bugs, so that only those clearly identified 
changes, and any parts not previously reviewed, need to be reviewed this 
time.
