[blarson@blars.org: Bug#323126: slate: ftbfs [sparc] Bus error]

[Brian Rice]

Hi, Nick!

I've been trying GCC 4.0 again on OS X Tiger/G5, and without that  
option it seems to work fine now. I'll check again and see what is  
actually breaking if I can.

I've also seen reports that GCC 4 can break assumptions about  
argument evaluation order, but I've not been able to reproduce a bug  
under it yet - when I do, I'll be looking for this kind of bug, and  
it's probably a good idea if others do, too.
