Summary: interface decl for PrelTup

Initial Comment:
My literate haskell script uses tupels with 38
elements. When using HUGS I get no errors and the
script is running as wanted. 
Compiling with ghc-5.02.2 following error occurs:

Switches_tupel.lhs:1:
Failed to find interface decl for
`PrelTup.(,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,)'
    from module `PrelTup'

GHC only provides tuples up to size 37. This is indeed a bug, 
and it's been on the list of things to fix for about ten years.  
But it's quite tiresome to do anything about and seldom bites.

I will update the manual; and I'll make the compiler give a 
more graceful error message.
