OK, it works for a hello world, it says the symbols are loaded.
Therefore, as was most likely, I've munged something.  How do I
interrogate object files to see which is/are missing the symbol data
(if that's what would throw everything else off the scent)?

Not much detail in there....

Thank you, and for the quick reply :-)
