[Bug c++/115792] GCC accepts [] throw () {}

https://gcc.gnu.org/bugzilla/show_bug.cgi?id=115792 --- Comment #9 from Jonathan Wakely --- throw() is not valid in C++23 at all (nor in C++20). GCC accepts it as an extension, but should probably warn with -pedantic. I don't think Clang is wrong here. Should we reopen this to add a pedwarn for
