So this argument isn't valid ;-) I think it was Hugs compliant as least for some revisions - I seem to remember looking at it before I switched to GHC.

Actually, how would you call it in Hugs? Just start it explicitly with the -98 flag?

For most extensions you use the -98 flag, for OverlappingInstances you use +o, and for CPP you use -F'cpp -P -traditional -D__Hugs__' (or similar). If FFI is required then call the program with ffihugs first. E.g. $> ffihugs -98 +o -F'cpp -P -traditional' Bar.hs $> hugs -98 +o -F'cpp -P -traditional' Bar.hs Hugs does not know about LANGUAGE pragmas, as those were added in GHC 6.8. And Cabal does not infer the need for -98 or +o based on the Extensions: field, so you'll have to add them to Hugs-Options: manually. Also, there are some bugs in Cabal preventing the mixture of CPP and FFI, even though this is fine in Hugs.
