fa55a6c92b50543352fef16e962511984998f123 c++: let plain -Wabi warn about future changes
c_common_post_options limits flag_abi_version and flag_abi_compat_version to
actual ABI version numbers, but let's not do that for warn_abi_version; we
might want to add a warning relative to a future ABI version that isn't
available in the current release, such backporting the PR120012 warning.
Also allow plain -Wabi to include such a warning without complaining that
it's useless.
Also warn about an unsupported -fabi-version argument.
gcc/c-family/ChangeLog:
* c-opts.cc (c_common_post_options): Let plain -Wabi warn
about changes in a future version.
