Hi Roger,
I figure I might as well push my luck. :)
Your patch appears to omit
program v
real, allocatable :: x(:)
allocate(x(100))
x = 0.
end program v
which is probably your
"[4] Extend infrastructure for arbitrary (run-time) length expressions,
such as a(1:n) = 0.0."
This idiom appears in a few places in Polyhedron, and I know it
is strewn throughout my own Fortran code.
Perhaps, the patch that Andrew has mention can deal with this.
