According to godbolt, it works in gcc 8.2 but fails in 7.3.

However, if you replace ( #i[0] ) == '-') with (i) < 0, then it works in lower versions too.

I find it weird that the author of this library chose to use ( #i[0] ) == '-') to test if the macro argument is negative, since it will fail if the parameter is not an integer literal.

(Update) According to OP's comment, the reason why (i) < 0 cannot be used is that it needs to classify -0 as negative too.

Here are some different approaches for GCC:
