What Gwynne said, but with one potential change, *some* versions of GCC require
a space before the last comma in order for it to be omitted if there are 0

#define GCLOGOC(format, ...) GCLogObjCMethod(self, _cmd, __LINE__,
NSStringFromClass([self class]), format , ## __VA_A
Ah, thanks guys! That works great :)

Hi all, I'm having trouble figuring this out.
I have a logging function thus:
voidGCLogObjCMethod( id obj, SEL selector, NSUInteger lineNumber,
NSString* tag, NSString* format, ... );
I'd like to be able to wrap this using a macro that automatically supplies the
object, selector, l
