+Some languages, like Fortran, have the ability to enter procedures at
+some place other than the beginning. One can declare an alternate entry
+point. The @code{N_ENTRY} stab is for this; however, the Sun FORTRAN compiler
+doesn't use it. According to AIX documentation, only the name of a
+@code{C_ENTRY} stab is significant; the address of the alternate entry
+point comes from the corresponding external symbol. A previous revision
+of this document said that the value of an @code{N_ENTRY} stab was the
+address of the alternate entry point, but I don't know the source for
+that information.
