Okay, I assume we are now at the problem in comment #58.  Would you upload the
final RTL
dump for "IsLower.c" ("-da" opttion will generate)?  It would also be useful to
find the change
which introduced the regression for "IsLower.c".

You could post the above patch with a ChangeLog to gcc-patches.  It's small
enough that a FSF
assignment shouldn't be needed.
