The patch tries to fix the error.
Probably the compilation error is caused by the option "-fstrict-overflow"
However the if statement is unsigned arithmetic (uint16_t) and there's
a similar arithmetic in xc_core_strtab_get() which gcc-4.2 doesn't complain.
So I'm not sure whether we should fix the another similar overflow checks which 
gcc-4.2 doesn't complain.
