Build failure with qemu-kvm 0.1x

Hi,

(Please keep me in CC as i'm not subscribed)

I couldn't achieve to compile qemu-kvm 0.1x.y series on my 32-bit host
system
I tried practically every target combination but nope. Here's the

When I run make V=1, it fails at:

Now looking at the code there, it seems that TARGET_I386 isn't defined
so p stays undeclared:

#ifdef TARGET_I386
    struct mapping *p;
#endif

Now I restart build with MAKE V=1 CFLAGS+="-DTARGET_I386", the errors
above disappears as p is now declared but:

and so on.. I suspect some locale specific things going on with i386 and
TARGET_I386 as i->I conversion is a little bit problematic in Turkish
collation. That's why I experimented a bit with LC_ALL=C but didn't
figure out anything useful.

And as I write this e-mail, I somehow managed to build it cleanly but
I'm sure that I didn't do anything special for that. I then make clean,
configure, make, and it failed again. Re-do the same cycle and now it
built correctly again for the 2nd time, what the hell is going on, any
ideas?

Thanks,
Ozan

And yes that was it:

target_arch_name="`echo $TARGET_ARCH | tr '[:lower:]' '[:upper:]'`"

this can't convert i386 to I386 which then appears in #ifdef
TARGET_I386. This will probably only affect languages in which
CAPITAL(i) = İ
CAPITAL(ı) = I

e.g. Turkish.

I work-arounded it by exporting LC_ALL=C at the beginning of the
configure script. It's on yours now to decide to fix it in upstream or not,

Thanks anyway :)
