I don't fully understand why we should apply the patch. With gcc 7.5 on mingw and the visibility.m4 that is in gnulib now: What is the result of the checking for simple visibility declarations... test? What are the effects: warnings? compilation errors? link errors? too many exported symbols? too few exported symbols? Maybe you also have a test case, that you could show? Bruno
