Compiling with GCC 4.6.0 20100925 produced warnings:
/src/qemu/target-i386/op_helper.c: In function 'switch_tss':
/src/qemu/target-i386/op_helper.c:283:53: error: variable 'new_trap'
set but not used [-Werror=unused-but-set-variable]
Fix by deleting the variable.
Alternatively the flag could be implemented by generating a debug
exception if the flag is set.
