Steve, one trick I use is copy the function heading and paste it twice so that 
you have a function prototype just above the function.  Then delete the static 
attribute on both.  All of a sudden you have a debug-able function.  Similarly 
in reverse with variables that are "optimized away" I put a "static" in front of 
them and I can then see them with gdb.  Most of the time this does not cause a 
problem, though you have to be aware of what you are doing. (debugging only 
obviously)
