Summary: pd-0.42 broken w/Tcl8.6 - interp->result

Initial Comment:
from tcl 8.6 direct access to field interp-result is not allowed anymore. you have to use Tcl_Get/SetObjResult.
patch fixes that

Message:
any luck with pd-devel?  you don't even need tcl.h or tk.h to build it, it
doesn't use the Tcl C API at all, so I think it should work fine on Tcl/Tk
8.6.

Message:
this issue it is just about Pd code that directly accesses a Tcl_Interp
field.

note that is perfectly legal in tcl 8.x to use Tcl_GetStringResult(interp)
rather than interp->result.

actually, if one upgrades to Tcl 8.6, can't compile Pd anymore.

Message:
since pd-vanilla 0.43 will most likely include the Tcl code from Pd-devel
0.41, I think it would be more likely that Tcl 8.6 support will happen with
that code.  Try testing pd-devel.

Also, since we are at it, Pd-vanilla doesn't work with Tcl/Tk 8.5 on Mac
OS X.  Pd doesn't even start, it just gives a "bus error".  I think there
are quite a few issues with the Tcl-C code in the Pd GUI, so I don't think
its worth trying to fix it.
