The error report comes when loading MarshalUtils.hs which is one of the new 
standard FFI libraries and defines a function called 'with'.  It's an 
incredibly useful library that would be painful to avoid.

I'd say the problem is in Hugs.  Why does it have a setting which prevents it 
from being able to load standard libraries?  It's now something like 2 years 
since we agreed to change the syntax, isn't it time that we removed support 
for the flag from the compiler?  I vote for eliminating the +/-W flag.
