Hi all!
C standard doesn't allow pointer arithmetic on void *.
Still, gcc allows it as an extension:
https://gcc.gnu.org/onlinedocs/gcc-4.8.0/gcc/Pointer-Arith.html
I can create a series of patches like this. Do we need it?
I don't think so, we only care about gcc & clang.
Still, if all supported compilers support the extension, then our
CODING_STYLE.rst should mention that it is safe to rely on the extension.
Also, where is documented which compilers are supported by Qemu?
It is checked in configure - gcc 4.8 or clang 3.4 or xcode clang 5.1
