 On platforms where @code{off_t} is a 32-bit type, @code{lseek} does not work
 correctly with files larger than 2 GB.  The fix is to use the
 @code{AC_SYS_LARGEFILE} macro.

+When the third argument is invalid, POSIX says that @code{lseek} should set
+@code{errno} to @code{EINVAL} and return -1, but in this situation a
+@code{SIGSYS} signal is raised on some platforms:
+IRIX 6.5.
