Bug in gcc CVS HEAD from a few days ago with alloca and stack alignment

[Kevin B. Hendricks]

Hi David,

Thanks!  

I changed STACK_BOUNDARY to 128 and rebuilt the entire gcc and now everything 
has started working including the gcj closure code and the gij interpreter.

Will you please commit a proper fix?  Franz's mail machine bounced my last 
mail so I don't think he knows about this problem.

Take care,

Kevin
