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);
