Hello,

I recently installed ActivePerl build 822 and discovered that my SWIG-based
extensions no longer compile. I am using Visual Studio .NET 2005 Enterprise
and SWIG 1.3.31.

apk_wrap_perl_d.cxx(1232): error C2159: more than one storage class
specified
apk_wrap_perl_d.cxx(1232): warning C4518: 'typedef ' : storage-class or type
specifier(s) unexpected here; ignored
apk_wrap_perl_d.cxx(1232): warning C4502: 'linkage specification' requires
use of keyword 'extern' and must precede all other specifiers

The error stems from this change in XSUB.h. The following line:

# define XS(name) void name(pTHX_ CV* cv)

Became:

# ifdef __cplusplus
# define XS(name) extern "C" void name(pTHX_ CV* cv)
# else
# define XS(name) void name(pTHX_ CV* cv)
# endif

It is the extern "C" that is causing Visual C++ to blow up, reverting back
to the old definition of XS fixes the problem.
