And a test for the prototype isn't necessary. Simply add a test for lseek64 and if this function is not available test for llseek with code like this:
That won't work, because glibc 2.0.7, which ships with Redhat 5.0, doesn't have lseek64. So if I adopted your suggestion, folks with RedHat 5.0 who tried recompile e2fsprogs would trash their > 2GB filesystems. Hence, I still have to test for the prototype.
This is what I mean about compatibility. What I do has to work for all versions of Linux, not just the bleeding-edge glibc. E2fsprogs will still work and compile for systems using a.out shared libraries. I just wish that the glibc developers spent as much time worrying about backwards compatibility issues as I do....
