Enough time has passed that you could simply commit these patches if 
you want to do so.  I don't see anything sloppy about the patches 
which would cause any concern.  I doubt that any of us are in a 
position to anticipate the full outcome from the patches.  The patches 
are not without a degree of risk, but it seems to me that the demand 
for testing (particularly the $pic_flag patch) will not be satisified 
unless the patches are in the mainline libtool code. The urgency for a 
new libtool release has now abated so this is as good a time as any to 
apply the patches so that proper testing can ensue.
