What is the politically correct way using the FFI and ghc5.03 (which I have just managed to compile from CVS) to import an externally defined object (not a function)? I have a source file containing the line foreign label "default_options" defaultOptions :: CString.CString for which ghc5.03 complains about "Warning: foreign declaration uses deprecated non-standard syntax", but which works anyway. However in my attempt to be a good little ghc user, I try instead foreign import "default_options" defaultOptions :: CString.CString (after deciphering with difficulty the Postscript version of the FFI document on this screen) but still get the deprecated warning. Then I try foreign import ccall "default_options" defaultOptions :: CString.CString and praise be, the deprecated message goes away. Only problem is, I now get a segmentation fault when I run the code . . .
