C compile problem

[Charles-Antoine Gauthier]

'or' is a reserved keyword in C++. Patches for this problem have already
been submitted as part of work to fuse the MBX860 and MBX821 BSPs and
PPC860 and PPC821 processors. Because of the substantial reorganization,
it was decided that the change would go in after RTEMS 4.5.0 was
released. For now, in
rtems/c/src/lib/libcpu/powerpc/mpc860/include/mpc860.h, just do this:

/*
 * Memory controller registers
 */
typedef struct m860MEMCRegisters_ {
  rtems_unsigned32        _br;
  rtems_unsigned32        _or;
} m860MEMCRegisters_t;


I quickly scaned of the eth_comm BSP files. It seems that the fields are
not used, so the above change may be the only one that is required. If
you are not using the eth_comm BSP, or if I missed finding the usage of
the fields, you will have to make the corresponding change in the source
files.
