Under the current condition that the relevant code here is not modified, this might be an acceptable temporary solution.

Patch 0002 adds GCC checking. Additionally, I tested the meson build system and saw no warnings with the `-Dc_args="-Wall"` configuration.

```
meson setup .. --prefix=$PGHOME -Dc_args="-Wall"
postgres(at)zxm-VMware-Virtual-Platform:~/code/postgres/build$ meson compile -j8
INFO: autodetecting backend as ninja
INFO: calculating backend command to run: /usr/bin/ninja -j 8
