Update:  I've confirmed that if I manually edit the generated makefile to remove the offending -ggdb and ensure the desired -gdwarf-3 is in place, I can work with the resulting lib.  However, since the automated build is within a much larger build and my issue only applies to a single configuration of many, my problem won't be solved until it can be addressed in the makefile that sets up and runs ./configure.  As before, all insight is appreciated and any solution will be applicable to all of us (I'm not the only one) who needs to debug with non-gdb debug info.  Thanks!

Thanks Chris,

I'm cautiously optimistic...  On one hand, assuming I'm running the experiment I think I am, it appear to work with your recommended change.  On the other hand, the resulting Makefile still includes -g and -ggdb on the CFLAGS line (which I *thought* I had previously determined wouldn't work, so it goes...).

An unexpected side benefit is that your recommendation also appears to have fixed another VERY obscure problem wherein the  static executable that includes cyassl (as well as other lib calls) no longer has the wrong instructions located at the locations the cyassl symbol references (but not for any of the other code...) in the loaded code (but *not* in the objdump -S listing of the same file as the one that is loaded).

Do you mind taking a quick sanity check of the following setup to see if there are other places we are making wrong assumptions on the ./configure setup?  I've just included extracts from the relevant Makefiles (there's a tree of included makefiles so these extracts come out of a couple of different files...)
