What is the effect of this change? The original code intended to have "float"
mean a 32 bit value, and "double" a 64 bit value. There aren't any larger
floats, so I defined the long double size as 64 also. Is the right answer not
to define it?
That part I understand, but why does the patch also remove FLOAT_TYPE_SIZE and
DOUBLE_TYPE_SIZE without explanation and without mention in the changelog?
