Moreover, C++98 defines it on the language level. As a result, the code is not buildable with C++ compiler or if iso646.h is included beforehand. According to comment, `sim_cpu_core` is mostly a clone of `sim_core`, so I renamed it to `byte_xor` as it's called in `sim_core`. sim/common/ChangeLog: * sim-core.h (sim_cpu_core): Rename cpu_core.xor to cpu_core.byte_xor. * sim-core.c (sim_core_set_xor): Likewise. (sim_core_xor_read_buffer): Likewise.
