Last verifiable bad optimization was in compiler version 4.4.5. I'm
currently using 4.4.6, and didn't try to do an optimized build on this
occasion. Main reason is how long it takes to do firefox builds on the
PWS 433au. The iceweasel/xulrunner build took over 12 hours without
optimization, and turning on "-O2" both adds time to the build and
pretty much guarantees a broken executable when the smoke clears.

Allow me to confirm those suspicions :-). I *might* have the coding
skills to be able to do it, but it would take me far more time than I
have available to make it happen. I'm sure there's someone better
qualified.

ACK on Matt being interested but lacking time at the moment. I'm about
to "go dark" for a few days due to an upcoming wedding, but I'll be
happy to reengage the discussion next Tuesday.

I'd like to think "dpkg-buildpackage" has an option to build the source
package without having to redo the binary package builds. (I typically
do a binary-packages-only build to avoid clobbering the original source
package). Let me see what I can do about that before the weekend gets
here.
