so it's an accident then? why not just remove it?
I'm not at all convinced it's an "accident". The GNU C extensions
were never documented, but that doesn't mean that nobody used them.
The code I showed is just a logical consequence of the existance of
those extensions. I've certainly known that it will work for quite
some time, perhaps as long as 20 years. There's no way to know how
much code that depends on this is out there.
I'll repeat now what I said a few weeks ago: it's precisely because of
these things already being in GCC that the GNAT project chose GCC to
use as a backend.
In any event, there's no reason to remove this since we can easily support it.
