Not working with ghc 7.8.4

[Javran]

Cannot compile the current verion of hcc with ghc 7.8.4.
The following error raised during compilation:

[ 9 of 45] Compiling Halo.Shared      ( halo/src/Halo/Shared.hs, dist/build/hcc/hcc-tmp/Halo/Shared.o )

halo/src/Halo/Shared.hs:44:29: Not in scope: ‘tracingDynFlags’

After changing the missing definition to undefined, I got another error:

[27 of 45] Compiling Halo.PrimCon     ( halo/src/Halo/PrimCon.hs, dist/build/hcc/hcc-tmp/Halo/PrimCon.o )

halo/src/Halo/PrimCon.hs:40:6:
    Not in scope: data constructor ‘ADataCon’

halo/src/Halo/PrimCon.hs:73:10:
    Not in scope: ‘mkDataConIds’
        Perhaps you meant one of these:
          ‘mkDataCon’ (imported from DataCon),
          ‘mkDataConRep’ (imported from MkId),
          ‘eqDataConId’ (imported from TysWiredIn)

Thanks. This repository is not really mainained anymore.
The corresponding fixes to the tracingDynFlags and ADataCon errors are in danr/hipspec@215daaa
I'm not familiar with the mkDataConIds problem, though.
