Hi,

Even if the spec doesn't say that you need a warning, would you wish
to have a warning when the conversion alters or may alter the value? I
am not sure how fixed-point works but for example, int i = 1.2 is
valid in C, however, we have a new warning option Wconversion [*] to
warn that the 1.2 will be transformed to 1. Would you be interested in
such a thing for fixed-point values?

Cheers,

Manuel.
