Cassandra, but the only reason no one believes her is because she can't stop pretending to be joking to diffuse tension created by her dire warnings

OK so this is kind of a pain in the neck to do a lot of times but sometimes you can get the output if the C preprocessor.

Then through careful editing, you can kind of figure out what it's turning in to.

int main(...) {
   WEIRD_MACRO(1, 2);
}

Then you could just put comments above and below it, and run cpp -I/all/include/directories main.c

It will tell you the final output and also have debugging garbage about where each thing expanded from.

Not ideal, and also in a big project that uses a complex build tool it can be incredibly hard to get the cpp args, but it can help.
