Call gcc with '-x assembler-with-cpp' instead of '-x assembler'. On x86 and powerpc, the second form above was ignoring all the CPP lines and hence trying to compile x86 asm on powerpc and powerpc asm on x86.

Major refactoring of the way that UNPACK pragmas are handled The situation was pretty dire. The way in which data constructors were handled, notably the mapping between their *source* argument types and their *representation* argument types (after seq'ing and unpacking) was scattered in three different places, and hard to keep in sync. Now it is all in one place: * The dcRep field of a DataCon gives its representation, specified by a DataConRep * As well as having the wrapper, the DataConRep has a "boxer" of type DataConBoxer (defined in MkId for loopy reasons). The boxer used at a pattern match to reconstruct the source-level arguments from the rep-level bindings in the pattern match. * The unboxing in the wrapper and the boxing in the boxer are dual, and are now constructed together, by MkId.mkDataConRep. This is the key function of this change. * All the computeBoxingStrategy code in TcTyClsDcls disappears. Much nicer. There is a little bit of refactoring left to do; the strange deepSplitProductType functions are now called only in WwLib, so I moved them there, and I think they could be tidied up further.
