It's C++14 that the openjdk currently cares about. C++14 added
"empty-declaration" to the syntax for "member-declaration".
C++14 9.2 [class.mem]
https://www.open-std.org/jtc1/sc22/wg21/docs/cwg_defects.html#1693
The above "struct f" declaration warns with C++14 and -Wpedantic, but
shouldn't.
Tested with that struct as the only contents of "test.cpp" and this command
line for g++13.2.0:
g++ -c -Wpedantic -std=c++14 -o test.o test.cpp
