From: Sergei Golovan
Subject: Patch implements --with-tcl option which allows one to
configure tcLex using any installed Tcl distribution (version 8 or 9).
Also, TCL_MAJOR_VERSION is added to the list of substitution to
generate different filename for the library depending on whether
it's built against Tcl 8 or Tcl 9.
