I guess that this justify why after r219557 we don't have any longer a
FloatingRealToComplex implicit cast for `c' in `b = c + b' below, right?

_Complex float b;

void foo (void)
{
  float c = 1.0;
  b = c + b;
}

The puzzling thing is that we still generates implicit
FloatingRealToComplex implicit cast for:

_Complex float b;

void foo (void)
{
  int c = 1;
  b = c + b;
}

Is this a bug?

I'm also wondering if it is a savy choice (standard apart) to omit such
kind of implicit conversions from AST considering that indeed they
"happens" (taken for granted we have also other implicit casts that
standard does not strictly requires).

Opinions?
