[Qemu-devel] [PATCH] build: fix Win32 clean build

[Paolo Bonzini]

The version.o file did not appear explicitly as a dependency, and
this caused clean builds to fail.  Force its build by making the
Makefile depend on version.o.

(We cannot add it to libqemuutil.a, because it doesn't export any
symbol and thus would not be pulled by the linker).

Blue, Paolo's patch fixes a recently introduced build regression for MinGW.
Please apply it to git master.

I won't send a pull request because it is a build fix.

Paolo, your latest modifications added one more regression
because MinGW builds now compile files which are only needed
for user mode (= never for MinGW).util/envlist.c uses strtok_r
which is unavailable for MinGW, so we get a compiler warning,
but no linker error because it is unused.

Regards
Stefan

Yeah, this is a side effect of having an understandable directory
layout. :)  However I'd prefer if we added strtok_r to oslib-win32.c to
silence the warning, even if it's dead code.
