Alternate Entry Points
======================

   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 `N_ENTRY' stab is for this; however, the Sun FORTRAN
compiler doesn't use it.  According to AIX documentation, only the name
of a `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 `N_ENTRY' stab was
the address of the alternate entry point, but I don't know the source
for that information.
