Here's a quick and dirty patch that implements sizeof.  It doesn't 
handle arrays, as I'm not sure what the expected result for allocatable 
of pointer arrays as arguments (or expressions in general) is.  From 
what I gathered by googling around, sizeof can always be evaluated at 
compile-time.  But then it couldn't accept as argument expressions whose 
size is only determined at runtime.

Can somebody with access to the Intel compiler try this, and report the 
results, or whether it gives a compile-time error:

integer, target :: i(5)
integer, pointer :: p(:)

j = 2
p=>i(2:4)
print *, sizeof (p), sizeof(i), sizeof(i(j:2*j))
end

Cheers,
