+Mod_perl incorporates a Perl interpreter into the Apache web server
+so that the Apache web server can directly execute Perl code.
+
+Mod_perl links the Perl runtime library into the Apache web server
+and provides an object-oriented Perl interface for Apache's C
+language API. The end result is a quicker CGI script turnaround
+process, since no external Perl interpreter has to be started.

+From 82827132efd3c2e25cc413c85af61bb63375da6e Mon Sep 17 00:00:00 2001
+From: Steve Hay <stevehay@apache.org>
+Date: Tue, 1 Dec 2015 17:39:43 +0000
+Subject: [PATCH] Add support for Perl 5.22.x.
+
+As outlined by Leon Timmermans in [perl #123687]:
+
+  lookup %ENV's magic, and then replace the pointer to PL_vtbl_env with
+  a pointer to MP_vtbl_env. You may have to add some svt_copy magic to
+  make it cast MP_vtbl_envelem instead of PL_vtbl_envelem on the elements.
+
+with an added svt_local for the 'local %ENV' tests.
+
+While at it, augment t/modperl/env.t to check that deleting %ENV elements really removes them from subprocess_env. This highlights the need for modifying their vtable, currently in the modperl_envelem_tie() macro.
+
+(MP_vtbl_envelem probably shouldn't be a global variable, but the modperl_envelem_tie() macro needs it, and the perl vtables are global too anyway. I've made MP_vtbl_env global too for symmetry.)
+
+Based on ++Niko Tyni's 0001-Steps-at-Perl-5.22-compatibility-take-3.patch in [rt.cpan.org #101962].
