[Libguestfs] new warnings in hivex-1.3.10

[Olaf Hering]

hivex-1.3.10 does not pass the sles11sp3 post-build-checks anymore,
1.3.8 was still ok. The relevant output is:

...
[   57s] Hivex.xs: In function 'XS_Win__Hivex_node_name':
[   57s] Hivex.xs:236: warning: implicit declaration of function 'newSVpvn_utf8'

[  155s] E: hivex 64bit-portability-issue Hivex.xs:236, 384

How can this be fixed? I'm not seeing this in openSUSE 12.x.
