Perl_save_bool() has been added.
+Regexp objects (those created with C<qr>) now have S-magic rather than
+R-magic. This fixed regexps of the form /...(??{...;$x})/ to no
+longer ignore changes made to $x. The S-magic avoids avoid dropping
+the caching optimization and making (??{...}) constructs obscenely
+slow (and consequently useless). See also L<perlguts/"Magic Variables">.
+Regexp::Copy was affected by this change.

C<-DL> removed (the leaktest had been broken and unsupported for years,
use alternative debugging mallocs or tools like valgrind and Purify).
End of Patch.
