If you are saying that you leave it up to the compiler to decide how
to interpret any of the three above statements, then clearly whitespace
is *not* meaningless.  It might be compiler-dependent or something,
but no meaningless.  Unless you are saying that on a given FORTRAN
compiler, only one possible interpretation of all three statements
above is possible.  That would be surprising.
