That's a very recent addition, and we do try to keep an eye on such
things. The R symbol has been changed now.

This looks like a bug in your tkConfig.sh.  For example on Solaris it has

# -I switch(es) to use to make all of the X11 include files accessible:
TK_XINCLUDES='-I/usr/openwin/include'

and that is what R uses, specifically

  if test -n "${TK_XINCLUDES}"; then
    TCLTK_CPPFLAGS="${TCLTK_CPPFLAGS} ${TK_XINCLUDES}"
  else
    TCLTK_CPPFLAGS="${TCLTK_CPPFLAGS} ${X_CFLAGS}"
  fi

Or is tkConfig.sh not being found and you need to point configure at it?
