gcc a.cc -o a.out

where a.cc is a hello world program.

    emacs -Q
    M-x gdb RET

You will see such a warning:

(gdb) Warning: 'set target-async', an alias for the command 'set mi-async', is deprecated.
Use 'set mi-async'.

The option mi-async was introduced in 2014 [1], so I thought using "set
mi-async" is safe enough in wild.

Another bug is the latest gdb supports debuginfod, which allows users
download debuginfo from an http server. When the environment variable
'DEBUGINFO_URLS' is set, let gdb run in terminal, it will prompt

    This GDB supports auto-downloading debuginfo from the following URLs:
    https://debuginfod.archlinux.org
    Enable debuginfod for this session? (y or [n])

But M-x gdb will unconditionally type 'y' for us

    Debuginfod has been enabled.
    To make this setting permanent, add 'set debuginfod enabled on' to .gdbinit.

The only workaround is

    echo 'set debuginfod enabled off' >> ~/.gdbinit

It's inconvenient. IMHO, M-x gdb should handle this case.

GDB before 7.7 is still used in the wild, so I'd rather not break
support for those old versions.

I can't seem to figure out how to get the GDB version using a GDB-MI
command.  Any ideas?

You want -gdb-version, I believe.
