When I compile qemu with such as:
git clone https://git.qemu.org/git/qemu.git
cd qemu
git submodule init
git submodule update --recursive
./configure
make
There is error log:

cc1: all warnings being treated as errors
So, add an initiallization value NULL for fn to fix this.

to quote the compiler version.
