3.2.72-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: "Kirill A. Shutemov" <kirill@shutemov.name>

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)

     switch(bytes_in_carry) { /* how many bytes in carry */
     ^

Let's disable the warnings for code which uses perl.h.
