Re: [PATCH] support: Add TEST_COMPARE macro

It'd be cleaner and simpler to test for negative than positive integers.
"bool negative = n < 0;" extracts N's sign bit if N is signed and

I expect that GCC will eventually warn about such tautological
comparisons. The current approach avoids such warnings.
I don't know what the context for this new macro is, and like Andreas
I'm a bit puzzled as to its intended use.
The purpose is to check if two values are the same, and print them (and
record a test failure) if they are not.
Thanks,
