I've checked with the assembler expert, and indeed this is a Leopard  
feature that will not be supported in 10.4.

However, the llvm-gcc I built on (x86) 10.4 does the right thing; it  
doesn't get into that code.  This is some sort of configuration  
issue.  I'm asking around to figure it out.  What hardware do you have?
