7af99f422f expr.c: 
fix a braino that caused only sizeof expr to work
linker.c:
	print an error message if unable to open the lib
qc-parse.y:
	revamp expression parsing so casting is done via (type)expr rather than
	type(expr)

7542a2457f replace @argc and @argv with @args.count and @args.list. @args is of type 
@va_list making it possible (though not yet: need to implement structure
copy) to pass ... params around.

e17604f9c2 remove all arbitrary limits except for globals. they'll need a little more
