Are these really supposed to be a target interface?  They are not documented,
nowhere overridden, and besides, it would appear odd to have a
DECIMAL32_TYPE_SIZE of, say, 31 bits.
It seems these macros just serve to make the code more readable.
Maybe they should be moved to tree.h ?

Point taken.  Using sig_atomic_type as the hook name makes sense.
