Another bug I think

[Julian Seward (Intl Vendor)]

| ghc-5.00: panic! (the `impossible' happened, GHC version 5.00):
|         ERROR: Native code generator can't handle casm

casm's are deprecated; they should have been knocked on the head
years ago.  The Right Thing To Do (tm) is to rewrite your code to 
use the FFI.  Or are you saying that the casm is nothing to do with
you and turned up via inlining? (unlikely with -Onot).
