GCC and clang also error out for unknown option. What option caused your
program to fail to compile?

The patch is for the case with -Wunsupported. In such case a user will
is "Don't trap, only warning". There are many gcc options which tcc
don't support. But in many cases, this options are not important.
Changing a Makefiles is not a solution when trying to use tcc insteed
of gcc.
And a patch test command is:
 /tcc -Wunsupported -traditional -E tcc.c -o tcc.i

I'd prefer a patch that just gives a warning for unknown -W option. It would be just like if the detection was really bad. Doing the same for other options would be more risky IMHO. That would avoid rewriting the Makefile to only add switches to CFLAGS that are supported by the compiler as it should have been done ;-) (no blame, we all do this).
