Hmm, so I did start my oS13.2 i386 guest:
$ as --version

This assembler was configured for a target of `i586-suse-linux'.
So this target is "i586-suse-linux" and you said
"i386-unknown-linux-gnu". Could that be a difference?

No warnings.
If I do a separate .s test dummy, it doesn't bitch either:
$ cat t.s
.text
LOWMEM_PAGES = (((1<<32) - 0xc0000000) >> 12)
mov LOWMEM_PAGES, %eax
$ as t.s
$
Do we have some bleeding edge gcc5 rpms somewhere I could try?
Thanks Micha.
