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 for fn to fix this.

What compiler version is this ?
It's the latest version: v5.1.0-rc2, but VERSION shows that is 5.0.92.
Commit id is 5772f2b1fc5d00e7e04e01fa28e9081d6550440a
I asked for the compiler version, not the QEMU version :-)
Clang, gcc, OSX clang, something else, and which version number?
