There are two reasons that I will normally use for justifying variable
declarations and neither of them are to save space.

The first is #define macros. For example:

	#define	DEBUG(key,msg) {char buf[512];.... }

The second is to try to segregate the use of register variables.  I'm not
too sure this really has an effect in all compilers, but at least it gives
it a chance.
