Selects __PRETTY_FUNCTION__ or __func__. Linux assumes GNU, and chooses
__PRETTY_FUNCTION__ if gcc/g++ versions are favorable.
This also includes a fix in ax_c_var_func.m4:
AC_TRY_COMPILE will wrap the test in main{}, and then GCC will complain
about nested functions. Just use the original main{} body.
