Cool. Thanks, Jim!

It looks like there's still a minor correction that needs to happen. I
didn't get an opportunity to test the merged changes until they went
public, and there's actually a compile error in there now:

	../../src/z_Linux_asm.s: Assembler messages:
	../../src/z_Linux_asm.s:1590: Error: junk at end of line, first unrecognized character is `,'

With a quick bit of Googling, I found this:


In that bug report's comments, Daniel Jacobowitz clarifies that '@' is
an ARM comment marker, so using '%' is the preferred annotation. I've
compile and run-tested this on both x86_64 and ARM, and both work at
this point:

diff --git a/runtime/src/z_Linux_asm.s b/runtime/src/z_Linux_asm.s

Now to conquer the build issues on Mac OS X...
