The real case was a bit stranger than previous reply (simplifying to a 1-D
array) 

const int xdim = 7;	
const int size = xdim;	// was a function of all dimensions
int array[size];
...
error: initializer element is not constant
error: variably modifed 'array' at file scope

So a "const" is not constant, says the compiler.
