Taking the 'sizeof' an undefined structure returns a 0 rather than
generating an error.

e.g.
	main(){
		printf("sizeof(struct Undef)=%d",sizeof(struct Undef));
	}

will print 'sizeof(struct Undef)=0'.

This one bit me when I forgot to #include a header file, and my only
use of the structure in the file was through a 'sizeof' reference.
Debugging devices is hard enough without debugging the compiler too. :-(

Tip to Lattice C users:  If you've been frustrated by 'omd's inability
to disassemble load files, there is a partial way around it.  When you
link all your object files together, use the 'PRELINK' option to 'blink'.
You then get something very similar to a load file, but 'omd' will grok it.
