The parser is based on the actual ISO-C grammar in most places, and yes, it
translates the above code correctly. There were several places where the
original code was not ISO-C compliant, but I have fixed most of them, at least
the ones, I have noticed.

One of the remaining areas where cc65 is not very standard compliant is the
preprocessor. It doesn't know about the "defined" keyword, and uses the
expression evaluation of the compiler to save some code. As a result, it
accepts things like

	int i;
	...
	#if (int) (i)	/* Will take constant address of i */
	     ...
	#endif
