[Xquartz-dev] ALLOCATE_LOCAL / crashes

[Jeremy Huddleston]

So... I wonder if we should do this across the board when compiling  
X.  Other things than the server use Xalloca.h.  I'm thinking I should  
put it in my standard CFLAGS.  Am I being overly cautious and  
paranoid, or is that something worth doing?
