+=item djSP
+
+Declare Just C<SP>. This is actually identical to C<dSP>, and declares
+a local copy of perl's stack pointer, available via the C<SP> macro.
+See C<SP>. (Available for backward source code compatibility with the
+old (Perl 5.005) thread model.)

+=item is_gv_magical
+
+Returns C<TRUE> if given the name of a magical GV.
+
+Currently only useful internally when determining if a GV should be
+created even in rvalue contexts.
+
+C<flags> is not used at present but available for future extension to
+allow selecting particular classes of magical variable.

+=item PL_DBsingle
+
+When Perl is run in debugging mode, with the B<-d> switch, this SV is a
+boolean which indicates whether subs are being single-stepped.
+Single-stepping is automatically turned on after every step. This is the C
+variable which corresponds to Perl's $DB::single variable. See
+C<PL_DBsub>.

+
+When Perl is run in debugging mode, with the B<-d> switch, this GV contains

+=item start_glob
+
+Function called by C<do_readline> to spawn a glob (or do the glob inside
+perl on VMS). This code used to be inline, but now perl uses C<File::Glob>
+this glob starter is only used by miniperl during the build proccess.
+Moving it away shrinks pp_hot.c; shrinking pp_hot.c helps speed perl up.
