RE: can't compile ghc from cvs

[Julian Seward (Intl Vendor)]

I think it's a legitimate problem with the new driver.  I hit it myself
on Friday.  I think that the _Capitalised entity naming scheme is
being misinterpreted by pre-4.07 ghc's.

... and I see that Sven has already fixed it.  Cool.

Until recently (including 4.06) GHC confused variables having names
starting with an underscore followed by an uppercase letter with
data constructors. This has been fixed for 4.07, but as people are
supposed to be able to build 4.07 with pre-4.07 compilers, I'll change
those identifiers in the driver sources with something more defensive.
The commit will follow soon...

I've just realised that this is not the true story. You *can* build
4.07 with =4.06, but not the CVS version with anything 4.07. But
I'll fix it anyway.
