There's a small difference, which is that the code actually worked as
of that commit. I suspect this got broken by Robert's barrier-hacking
of a few months ago. I don't think I've tried the non-gcc build since
committing 89779bf2c8f9aa48 :-(

Seems reasonable to me. An empty external function should do the job
for any compiler that isn't doing cross-procedural analysis.
