Regardless of whether (when comparing floats with reals) compiler should
compare with full or truncated to smaller type precision, current behavior
seems to be inconsistent with spec. According to the spec in section "Equality
Expressions" floating point types are compared bitwise. This means that if two
floats are compared, compiler need not care about extra precision but currently
it compares 32 bit with 80 bit (issue is better revealed in 8745). 

But if this is feature and not a bug, spec should be changed and better explain
the issue.
