Sorry, you must have missed the two follow-up messages:
http://lists.gnu.org/archive/html/qemu-devel/2008-08/msg01252.html
http://lists.gnu.org/archive/html/qemu-devel/2008-08/msg01292.html

So instead of CTYPE macro, there should be qemu_toupper, qemu_isalpha
etc. which handle char arguments correctly even when sign extension
happens.
