[Bug driver/41024] driver passes wrong parameter to as

It's because of this in gcc/config/i386/mingw-w64.h:
#define ASM_SPEC %{v:-V} %{n} %{T} %{Ym,*} %{Yd,*} \
%{Wa,*:%*} %{m32:--32} %{m64:--64}
The %{v:-V} part is what's triggering what you see. Now, the question is why
is your as rejecting the -V option? My linux as accepts it, my darwin as also,
but i586-pc-mingw32-as doesn't...
After further investigation, it seems that handling the option -V on i386
processors is only done for ELF targets; can't even begin to think of a good
reason for that, but that's what gas source code says. So, I recommend the
following (untested) patch to GCC:

Ok, could you sent a patch for it. It is pre-approved by me.

I am retesting it. I think {v:-v} is better here.

This patch works fine. Could you post a patch for it. It is pre-approved.
