Hello Sumanth, and everyone,

Thank you for your reply.

I think you mean MIN_UNITS_PER_WORD in gcc/config/h8300/h8300.h.

Unfortunately it was defined 2.

Here are excerpts from gcc/config/h8300/h8300.h that is converted according 
to patch,
which has been previously sent as 
patch-sources/gcc4.4.0-patch-converted-sources/h8300.h.
