[Qemu-devel] [PATCH] fix for TEST_BSX in test-i386.c

["Zeev Tarantov" <zeev.tarantov@gmail.com>]

Hello!
In GCC 4.3.1 I get syntax errors building test-i386.c with any
optimization level higher than -O0.
I assume this does not happen with GCC 3.X.
The following patch fixes the problem. I believe that it is more
correct and not just a quirk of gcc.
After applying this, the tests produce expected results (and pass).
If this is a double post, I apologize - I have tried sending this
using gmane without being subscribed to the list.
