This might be simpler for people to modify since it abstracts out the
version checking.

Suppressing compiler warning on Debian 12/gcc 12.2.0

[Bruce Momjian]

Being a new user of Debian 12/gcc 12.2.0, I wrote the following shell
script to conditionally add gmake rules with compiler flags to
src/Makefile.custom to suppress warnings for certain files.  This allows
me to compile all supported Postgres releases without warnings.

I actually didn't how simple it was to add per-file compile flags until
