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. See
http://community.haskell.org/~wren/cabal-ffihugstest for more details.
