Comment:

 Unfortunately, with this patch or something like it, I am dealing with
 constant break on PowerPc like this:

 {{{
 compiler/nativeGen/X86/Regs.hs:61:1:
     Warning: The import of `CmmCallConv' is redundant
                except perhaps to import instances from `CmmCallConv'
              To import instances alone, use: import CmmCallConv()
 }}}

 I am all for the long term goals of fixing this, but would to make sure
 that PowerPC continues to build correctly so I can work on the other
 outstanding PowerPC related tickets.
