| 	252.eon includes the following code:
| 
| ggRasterSurfaceTexture::ggRasterSurfaceTexture( istream& in) {
| ...
|    unsigned char red, green, blue;
|    in.get(red); // eat a byte

Ah, then, that is bogus.

| ...
|           in.get(red);
|           in.get(green);
|           in.get(blue);
| 
| 
| Why did this work before?

I have no theory for the moment.  Do they still have a working SPEC on eon?
If GCC accepted the above in the past, it was simply by mistake.

No, I don't beleive so.  You cannot pass a T& when a U& is expected
unless U and T are related.  And the case above is explicitly invalidated.
