patch applied (ghc): Lint should check for duplicate top-level bindings with same qualified name

[Simon Peyton-Jones]

Now that *is* strange. The change only affects Lint, ant it affects Lint only by gathering the top-level names (done already) and checking that "M.x" doesn't occur twice (for any M, x). I would not have expected that to double space usage!

Might you investigate a bit more with your profiled compiler?

Thanks

Simon

| This patch makes T1969 fail on the 7.0 branch (and would also make it
