[xcrysden] compiling on tcl 8.6

[Lorenzo Paulatto]

Dear XCD users,
in case you are trying to compile XCrysDen with TCL 8.6 and you're
getting this error:
  Tcl_Interp’ has no member named ‘result’

you have to add "-DUSE_INTERP_RESULT" (no quotes) to the CFLAGS in
Make.sys. The code will then build with tcl8.6 (to be honest, I only did
bindist-shared).

This should solve the problem, I don't know if the feature is planned
for removal eventually but give the frequency of TCL releases I think
there's no immediate need to worry.
