This patch has broken the CIFuzz automatic check somehow. |
Assume that a compatible `-fvisibility=hidden` option is available and that the compiler handles correctly `#warning` macros. Restrict the visibility test if `-Werror` is unrealiable to protect for compilers like xlc or systems like cygwin that might allow the compiler flag without errors but wouldn't work. While at it, lower the minimum autoconf required to the one that introduced the latest macros and tested in OpenBSD 7.5 with automake 1.9.

Tested with the latest version of SunPro and TinyCC. It would also allow for other clang proprietary derivatives.
As usual, would fall cleanly for the cases where there is no support for
