Those files shouldn't have the `-std=c++17` attribute passed to the `command` in `compile_commands.json`, probably they should have `-std=gnu99` like the rest of the `c` files.

Those files shouldn't have the `-std=c++17` attribute passed to the `command` in `compile_commands.json`, probably they should have `-std=gnu99` like the rest of the `c` files. Probably they must be set in the `moz.build` directory, something like `CFLAGS += ['-std=gnu99']`?
