AVR-Chat

While I was tracking down my 'clobbered stack' problem I implemented a couple of
function Enter/Exit macros that I placed in functions in an effort to isolate
exactly where the problem was occurring.

On entry I reported the function name as well as the stack pointer, on exit I just
reported that I was exiting "xyz".

I used the __func__ compiler symbol which worked fine, except, as far as I can tell
WinAVR insists on placing the function name in SRAM space as opposed to program
space and I am way shorter on SRAM space than I am on program space (ATMega32).

Is there a way to have WinAVR put the name in program space?  (without me having to
retype each name ...)

Is there another facility I should use?

As I type this, it occurred to me that I might be able to write a preprocessor macro
(w/variable args) that could wrap function declarations and returns.  For some
reason it strikes me as not a good idea.  Might it screw up readability,
'lint'/re-formatters, or confuse the IDE editor (Code::Blocks)?

I suppose another option would be a utility that knew how to parse C and add the
program-space function name as a function-scope variable for me ...

Or, maybe I should just hope I never have to do that again :-)
