12 bytes, to preserve alignment. A `struct type' representing
such a floating-point type would have a `length' value of 12,

about machines whose bytes aren't eight bits long, or who don't
have byte-addressed memory. Various places pass this to memcpy

other places expect they can calculate addresses by adding it

some DSP targets, in which HOST_CHAR_BIT will (presumably) be 8
and TARGET_CHAR_BIT will be (say) 32, this is a problem.
One fix would be to make this field in bits (requiring that it
always be a multiple of HOST_CHAR_BIT and TARGET_CHAR_BIT) ---
the other choice would be to make it consistently in units of
HOST_CHAR_BIT. However, this would still fail to address
