D.gnu - undefined identifier destroy

I get the an "undefined identifier destroy" message when trying 
to compile the following with GDC.

void main()
{
     X x = new X();
     destroy(x);
}

...but it compiles fine in DMD 2.065.0.

I'm using a week-old build of 4.8.2.  Is this not implemented yet?

Thanks for the reply. I just rebuilt, and I get the same error. Are you using the GDC 4.8 branch with GCC 4.8.2? My build is an ARM Cortex-M cross compiler, but the latest Arch Linux 64 GDC package also fails with the same error.

Destroy was added to druntime years ago: https://github.com/D-Programming-GDC/GDC/blame/gdc-4.8/libphobos/libdruntime/object_.d#L2257 (It's implemented in the library, so if you want to use it on bare-metal without druntime you'll have to rewrite it ;-)

is no druntime, unfortunately.

Ah! silly me. Thank you. I expected a link error, though, for a missing library function.

which calls finalizer (see object.di in GDC source). so compiler have no way to know that it should do something special with this identifier.
