Hi Everyone, The page <https://www.gnu.org/software/autoconf-archive/ax_gcc_builtin.html> does not list __builtin_offsetof in the list of documented builtins. But the page says "Unsupported built-ins will be tested with an empty parameter set and the result of the check might be wrong or meaningless so use with care." Is it safe to use ax_gcc_builtin to detect __builtin_offsetof? Sorry to ask. Google is not returning useful results. Thanks in advance.
