Yes, it is generated, but it is also present in the source directory in 
recent tarballs on hydra.  When building in a separate build tree from 
the sources, the -I compiler options are such that the mxarray.h file 
from the src directory will be used.  That's the wrong version since it 
wasn't generated correctly for 64-bit Windows systems.
