So right now on Mac we seem to be doing (for the nightly builds):

   ac_add_options --enable-optimize="-O2 -g"

With gcc on Linux, we are doing:

   ac_add_options --enable-optimize="-Os -freorder-blocks -fno-reorder-functions 
-gstabs+"

based on some performance testing way back when.

I agree that it would make some sense to at least try the same thing on Mac.
