question regarding muliple compilations (for -g vs -O3)

[Rick Riolo]

Now that swarm-1.3 uses a new configure/make process,
what is the best way to have two swarm compilations, 
one (the default) with -g for debugging), and another 
(without -g and -O3 say) to run smaller and fast?
And of course what I would like is to have just one src for
both versions.

Could I:
- have /s/Swarm/swarm-1.3 for the default version,
  including storing the source there, and
- have another directory /s/Swarm/swarm-1.3-opt
  which doesn't have source but in which I run my configure
  and make script using:
     --srcdir=/s/Swarm/swarm-1.3
     --prefix=/s/Swarm/swarm-1.3-opt
  to have it build libs, includes, etc, for my optimization version?

If that works, what is the best way to tell the opt version
to use -O3 instead of -g ?
Maybe I just need
   make SHELL=/usr/local/bin/bash CFLAGS=-O3
to override the CFLAGS?

Thanks for the advice.
