    What has this to do with irresponsibility? It certainly was a mistake
    to add llseek but when I realized this the damage was done (i.e., the
    ABI was used). But since I never added the prototype this keeps the
    attention away from this function which never ever should be used.

    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:

    [AC_CACHE_CHECK([for usable llseek], e2_cv_usable_llseek,
    [AC_TRY_LINK([#include <stdio.h>],[#if __GLIBC__ == 2 && __GLIBC_MINOR__ == 0
    #error "not here"
    llseek (0, 0, 0);
