Second: I was in error on the optimization issue! When we converted over to CW 5.0.2 from 4.x apparently the optimization settings in the projects did not carry through. That was some time ago, and at the time we noted that our loader would not fit when compiled with the new version. I finally got around to it again last night, so that was the genesis of my frustration with the optimizer. I don't know what was going on last night, but for some reason changing global optimizations from faster to larger (I think I was using the radio buttons) had no effect. I remember trying both full left and full right on the slider, and somewhere in between. I threw up my hands in disgust, and started looking at the task of optimizing the "C" expressions. Then, this morning, I got hit with Art's and Ron's messages, and I may have lost a bit of sanity.
In summary, using the first level does make a significant difference in code space, the loader now fits into memory. However, when I use that setting on our downloaded application, the compiler generates warnings on one developer's machine but not 2 others. Also, I have noticed that some files are forced to recompile after changing the settings and not others. Perhaps this is a symptom of the toolset that leads to the label of "Buggy." I have worked with the Microsoft tools, the LLC compiler, the Tornado version and other versions of the GNU compiler. While they all have "Quirks", and I have only been using "C" on and off for about 15 years, this toolset does seem to generate more unexpected behaviour. When I move the slider to ask for smaller code, or click the Radio button for smaller code, I have seen it increase the code size!
Again, I regret having trashed the good programmers who must know something about optimizations after all!!!
