I remember prety clearly, that I run into stubble problems
with definitions of various types according to machine word - for instance
defaults.h says:
#define DOUBLE_TYPE_SIZE (BITS_PER_WORD * 2)
and makes double TFmode.
I've looked at other backends (I think sparc) and seen that it defines all types
so I came to conclusion that it is probably cleanest.
Checking more detaily I need to define DOUBLE/FLOAT/INT/SHORT, since they are
BOTS_PER_WORD based.
I can omit WCHAR and BOOL. Would you prefer to do that?
