GHC 4.04 patchlevel 1 released

[Simon Marlow]

Hi Folks,

I've updated the 4.04 distributions on the web site to patchlevel 1.  Please
install the new version if you're using the original 4.04, since it contains
a fix for at least one bug that could cause spurious crashes.

Also in this update:

        - several bug fixes
        - gcc 2.95 compatibility
        - non-blocking I/O support for Concurrent Haskell,
          including threadWait{Read,Write}, and threadDelay.

Enjoy!

Simon
