I can't forsee the potential performance ramifications, but frankly -fvia-C has been deprecated/not-advised-for-use for quite a while now, and I wonder how many of these programs just have not been updated/tested with the native code generator since they were written.
In any case it's not an option anymore, so your only choice is to nuke it from orbit (orbit being the Makefiles.)
Well, the better option would be to try with the NCG, and also with LLVM (the -fllvm flag). While the NCG is certainly competitive for idiomatic Haskell code, it's likely to be a bit behind when it comes to heavy C-in-Haskell code like what often gets submitted to the shootout. LLVM seems likely to do better in some cases. -- Chris
