...Could it be that both of these compilers derive from the original Berkeley
...Unix f77 compiler?
The likely behavior on those compilers which ignore the error is to choose
one argument (probably the later one) and use it throughout the subroutine.
In any case, this looks like a clear programming error to me.
A Convex compiler gives an error complaining X being declared twice and
about the dummy argument appearing twice.
