Hi, I want to invoke the C-function 'dlsym', which has three
possible options for a parameter of type (void*):
- NULL
- void* to a string, i.e. CString in Haskell
- RTLD_NEXT = (void *)(-1)
The first two ones are no problem, I can use a CString and
'nullPtr'. For the last one, I have the

And why didn't it happen in a compiled version?
Because the 'optlen'
At [EMAIL PROTECTED] I asked the following:
this works
data Exists f = forall x . E ( f x)
this doesn't work
newtype Exists f = forall x . E ( f x)
Hugs accepts both.
It there a reason why existential quantification does not work with a
newtype, or is it just
