By default compilers may not treat attribute warnings as errors when encountering an unknown
__attribute__
, unless some error option is provided (-Werror=attributes, -Werror...). This fixes the check and wraps it into a separate M4 macro to be extendable in the future if needed. It checks if conftest.err file was generated by the compilation check when warnings appear. Also, PHP check is a bit customized by using__alignof__
keyword, so it is left in there for now to not break existing checks.
