This would mean that 'derivable type classes' can't be used for
HOpenGL's data types. In other word, the user would get something like
MyGenerics.hs:41:
Can't derive generic code for `blah'
because the instance type constructor `PolygonMode' was not compiled with
-fgenerics
In the instance declaration for `Blah PolygonMode'
where PolygonMode is an algebraic datatype from HOpenGL. Hmmm, this is
not acceptable for a library IMHO. OTOH, with -split-objs the additional
functions for generics probably won't end up in the final executable if
generics are not used, correct? In this case, it's only lib*.a and HS*.o
which are getting bigger, which not a serious problem.
Cheers,
S.
