If you look at the code, there is already a macro to get the type

So the correct fix is to make sure that the makefile sets the macro

Perhaps it would work if it were just "wired on".  I don't actually
know if any systems that Opensswan supports actually leave out the

So: I'd revert these changes and get SCANDIR_HAS_CONST right.
