Re: [Qemu-devel] (TEST) CFLAGS options + qemu 1.60

["André Braga" <meianoite@gmail.com>]

That's a (now-)known bug... in GCC. =P

It's good to see that more people are fiddling with the CFLAGS :D

BTW, the makefiles are wrong in the sense that they don't respect the
environment-set CFLAGS. I'll send a patch later tonight.
