The countless warnings are "normal" because you use MinGW which is
unmaintained since several years.

There is a better alternative: use Mingw-w64. It compiles QEMU (*nearly)
without warnings, solves the ffs problem and has the additional benefit
that it supports both 32 bit and 64 bit builds.

Maybe we should drop MinGW support completely...

*nearly means that there are still warnings for format strings in C++
code. You won't see them if you don't install a C++ compiler, but as you
are interested in ARM and the C++ code is needed for the ARM
disassembler, you might want it.
