Noah Watkins ac044812d0 assert: choose function-var name on non-gnu ... 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. diff --git a/m4/ax_c_var_func.m4 b/m4/ax_c_var_func.m4 index 0ad7d2b..8b57563 100644 --- a/m4/ax_c_var_func.m4 +++ b/m4/ax_c_var_func.m4 @@ -57,9 +57,9 @@ AC_DEFUN([AX_C_VAR_FUNC], [AC_REQUIRE([AC_PROG_CC]) AC_CACHE_CHECK(whether $CC recognizes __func__, ac_cv_c_var_func, AC_TRY_COMPILE(, -[int main() { +[ char *s = __func__; -}], +], AC_DEFINE(HAVE_FUNC,, [Define if the C complier supports __func__]) ac_cv_c_var_func=yes, ac_cv_c_var_func=no) ) Signed-off-by: Noah Watkins <noahwatkins@gmail.com>		2013-11-06 14:16:28 -08:00
