FWIW, I'd rather see you stick with REAL_TYPE.  I think that decimal 
floating point is similar enough to binary floating point to make that 
worthwhile.

What I would hope would work would be modifying real.c to (a) directly 
suport the decimal format for storage, and (b) update the emulation of 
floating-point operations to work correctly on the decimal format.  I 
definitely agree that translating into the binary format is likely to 
result in various errors.

I don't have an opinion on exactly what method of modifying real.c would 
be cleanest.
