The code for passing on local variable information in the c++ parser
is working now.  It's been a while since I poked around in there, but
it doesn't use SN_LOCAL_VAR_DEF, it uses SN_REF_SCOPE_LOCAL and
SN_REF_TO_LOCAL_VAR, although it has been long enough for me to
forget how.  I think SN_REF_SCOPE_LOCAL is used to add a local
variable to a function (as in the declaration), and SN_REF_TO_LOCAL_VAR
used to mark uses of the declared local variable.

I could of course be completely wrong.

Hmmm, not sure.  They could well be a problem with SN_LOCAL_VAR_DEF.

Local variables should be working in C/C++ use now.  You should
see them in the Xref window.
