Description: fix type mismatch of MGVTBL.svt_copy namelen argument
 Since Perl 5.12, the type of the namelen argument of the svt_copy member of
 MGVTBL struct has changed its type from `int` to `I32`.
 .
 Perl commit:
 https://github.com/Perl/perl5/commit/3468c7eaa8d7687e8ae89928492b408a4d6c752f
 .
 On 64-bit platforms `int` and `I32` are both 32-bit integers, but on 32-bit
 platforms I32 is `long int` and a simple `int` is 16-bit.
