Yes indeed, this is one of those well-known (ie not at all well
known, but folk lore) problems with overlapping instances, at least in
programs where different instances can be in scope at different times.
I think these examples are subtly different (eg, some trip up Hugs as

I'm not super experienced with the FFI (foreign function interface); I
only used C types that you can get from #include HsFFI.h, like
Word32.
You might need to make Sigval an instance of Storable, or do some
magic with ForeignPtrs. Good luck! :)

Also, if you always plan to partially apply your notification function
and you just want a simple callback:
void (*pCallbackFn)(void);
You should be able to do something like this:
type Callback = IO ()
foreign import ccall wrapper mkCallback :: Callback - IO (FunPtr Callback)
You can then

Hello,
The syntax highlighting file for literate haskell in vim says that its

find this relevant.
In literate haskell files, vim optionally highlights the non-code text
