[libunwind] c++ patch for libunwind-0.91

[A N Burton]

Please find enclosed a patch that will add the
appropriate extern "C" linkage specification
to the exported headers.  This patch should
be applied from the root of the distirbuted
hierarchy, and applies to version 0.91.

The motivation behind this patch is to allow
libunwind to be called from both c and c++.

Regards,

Ariel Burton
