Good point.

However, try-cc does not run the resulting program after
compiling it, so the test still succeeds.

What you want to do is make the compilation fail;
to do so, move your test here:

#include <Python.h>

#if PY_VERSION_HEX >= 0x03000000
#error "Python 3 is not yet supported; set PYTHON{,_CONFIG}"
int main(void)
...

P.S.
