Well, looking at the code I thought that it should output both,  because gcc 
is supposed to support non-constant initializers.  But I am not really any 
help, because I do not know enough about gcc to say.  One thing that I do 
notice in your example is that the printf should be leaving an integer in the 
__uwf_1 position of tmp but how could there be space for it (as uw_unit should 
occupy 0 size) ...
