3.4.108-rc1 review patch. If anyone has any objections, please let me know.
------------------
commit 575bf1d04e908469d26da424b52fc1b12a1db9d8 upstream.
perl.h from new Perl release doesn't like -Wundef and -Wswitch-default:
/usr/lib/perl5/core_perl/CORE/perl.h:548:5: error: "SILENT_NO_TAINT_SUPPORT" is
not defined [-Werror=undef]
#if SILENT_NO_TAINT_SUPPORT && !defined(NO_TAINT_SUPPORT)
^
