Okay, of course it is a bug.  But the problem is that cc is not detecting
it and just compiles it that way.  Shouldn't there be something in cc so
that a warning could appear.  Say like:

WARNING! Float not casted in to different declaration.

This is actually a serious error because anybody could do this and then
totally crash the system!
