Make `SCM' type definition acceptable for C++ compilers.

Browse source 
* libguile/tags.h (SCM) [SCM_DEBUG_TYPING_STRICTNESS == 1]: Use a named
  struct to avoid errors from C++ compilers such as "error: non-local
  function ‘<anonymous struct>* foo(<anonymous struct>*)’ uses anonymous
  type".  This fixes a regression introduced in
  c6054feaf0 ("Add support for static
  allocation of cells, strings and stringbufs.").  Reported by Linas
  Vepstas <linasvepstas@gmail.com>.
