support: Increase usability of TEST_COMPARE
The previous implementation of the TEST_COMPARE macro would fail to compile code like this: int ret = res_send (query, sizeof (query), buf, sizeof (buf)); TEST_COMPARE (ret, sizeof (query) + 2 /* Compression reference. */ + 2 + 2 + 4 + 2 /* Type, class, TTL, RDATA length. */ + 1 /* Pascal-style string length. */ + strlen (expected_name)); This resulted in a failed static assertion, "integer conversions may alter sign of operands". A user of the TEST_COMPARE would have to add a cast to fix this. This patch reverts to the original proposed solution of a run-time check, making TEST_COMPARE usable for comparisons of numbers with types with different signedness in more contexts.
