dnl (Commenting these out in the following list makes configure barf)
dnl
dnl NOTE - before you optimise away the weird SUCCESS_CFLAGS thing, understand the following:
dnl clang doesn't exit with an error for an unsupported warning flag by default.
dnl clang has -Werror=x to promote a warning to an error, but gcc treats that as an error
dnl clang and gcc both support -Werror to promote all warnings to errors
dnl initialising and returning the value of arse removes the gcc warning that arse isn't used.
dnl So, until a better solution is found, -Werror is added while testing -W flag support.
dnl
dnl Warnings added to C should also be added to C++ compiler list. Except these ones because novte:
dnl -Wstrict-prototypes (g++ warning: "cc1plus: -Wstrict-prototypes is only valid of C/ObjC not C++" - but zero exit code)
dnl -Wformat-signedness (novte warnings - these could be addressed with source changes)
dnl
dnl C++ warnings implied by other settings but explicitly disabled:
dnl -Waddress-of-packed-member (novte warnings)
dnl -Wchar-subscripts (novte warnings)
dnl
dnl -Wunused-but-set-variable is enabled by -Wall in GCC >= 4.6 but doesn't
dnl exist in clang < 13.0. clang-tidy implements this check though, so our
dnl Github code analysis runner should find these issues pre-clang 13.
