SWIG uses XS() like this (in the perlrun.swg template):

typedef XS(SwigPerlWrapper);
typedef SwigPerlWrapper *SwigPerlWrapperPtr;

This breaks if XS() includes the 'extern "C"' decoration under C++.
The appended patch provides an XSPROTO() macro that could be used
by SWIG instead.

(Patch from Jan Dubois to fix breakage caused by #28734.)
