The "hsc" (Haskell compiler proper) binaries in the standard binary
bundles ghc-0.29-alpha-dec-osf1.tar.gz,
ghc-0.29-sparc-sun-solaris2.tar.gz, and
ghc-0.29-sparc-sun-sunos4.tar.gz are not GranSim-friendly (GranSim is
GHC' parallel-machine simulator subsystem).  They will give say
"*** WARNING: bad option: -fgransim".

To fix this, we're providing replacement "hsc"s for those platforms,
in the files ghc-0.29-gran-hsc-alpha-dec-osf1.gz,
ghc-0.29-gran-hsc-sparc-sun-solaris2.gz, and
ghc-0.29-gran-hsc-sparc-sun-sunos4.gz.  Grab the one you want, gunzip
it, and drop it in place of your normal "hsc" binary.

Both the "unfixed" and "fixed" binaries are fine for non-GranSim
purposes.
