The flag -fext-core is a red herring. GHC assumes any module with no "module" declaration is actually called Main and hence insists on a main declaration.
...or to be precise, it means module Main (main) where {...} ...and this is what the Haskell 98 standard requires (section 5.1). Thus, main has to be defined/imported in said module, so that it can be exported thus. (Also, GHC feels free to remove/optimize/change definitions that are not exported...) -Isaac
