updated for version 7.3.653
Problem:    MingW needs build rule for included XPM files.  Object directory
            for 32 and 64 builds is the same, also for MSVC.
Solution:   Add MingW build rule to use included XPM files.  Add the CPU or
            architecture to the object directory name. (Sergey Khorev)
