gcc v12 warnings

[andrewgait]

Compiling with arm-none-eabi-gcc v12.2.0 gives strange-looking warnings like the following:

arm-none-eabi-gcc -c -mthumb-interwork -march=armv5te -std=gnu99 -ffreestanding -I /Users/user/code/spinnaker/git/spinnaker_tools/include -Wall -Wextra -Wold-style-definition -DPRODUCTION_CODE -DPROFILER_DISABLED -Ofast -DAPPLICATION_NAME_HASH=0xfdeb3b58 -I /Users/user/code/spinnaker/git/SpiNNFrontEndCommon/c_common/models/system_models/modified_src/ -g -o /Users/user/code/spinnaker/git/SpiNNFrontEndCommon/c_common/models/system_models/build/extra_monitor_support.o /Users/user/code/spinnaker/git/SpiNNFrontEndCommon/c_common/models/system_models/modified_src/extra_monitor_support.c

It seems from https://gcc.gnu.org/bugzilla/show_bug.cgi?id=105523 as though this is a bug that is yet to be resolved, so I would suggest keeping an eye on the status of that bug to see what happens there.
