Hi,
This patch fixes a compiler crash for alpha-vms.
Back-ends should not lie to the middle-end by defining macros to plain abort
since the middle-end is entitled to infer properties from their existence.
The correct thing to do is not to define the macros in the first place.
Committed on trunk.
Tristan.
