THIS IS NOT A GHC PATCH, it's a patch for Happy that I didn't know where else to send. I still have no idea where to discuss Happy and Alex modifications (things get lost too easily in haskell-cafe, and Happy and Alex aren't exactly libraries?); (and I don't know if I should consider myself to have commit privileges to them either, when my patches aren't ones that need review)

Anyway, these patches were needed for GHC to compile itself using `happy`-without-`-agc`, and without indiscriminately enabling -fglasgow-exts for the following compilation.

  * bugfix: allow multi-word token-type using parentheses everywhere needed

Thu Dec 27 11:54:46 EST 2007  Isaac Dupree <[EMAIL PROTECTED]>
  * refactor HappyReduction-generating code (no semantic change)

Thu Dec 27 12:04:54 EST 2007  Isaac Dupree <[EMAIL PROTECTED]>
  * self-expand HappyReduction for more Haskell98 compliance
  It's not too bad at all since it's only duplicated in two
  places.  Happy without -agc is most likely to be used by
  the compilers other than GHC anyway.  Should I really
  put those comments into the output file, or is it better
  just to remove the references to the old type-synonym?
