[Bug c/14384] New: Invalid use of extra precision floating-point with -O0 optimization

[anz at obs-nice dot fr]

Arithmetic involving a float and a "lesser" type should be done in float in C89,
at least when optimization is turned off.
In some cases (shown in the attached program), the arithmetic is done in double,
carrying extra precision, which is *not* wanted, and makes the program results
different from those on other machines.
