I just changed 
    bind("ecn_", &ecn_);
to 
    bind_bool("ecn_", &ecn_);
in tcp.cc, so that you can now set ecn_ either as true/false or
as 0/1.  

The ECN web page ("http://ftp.ee.lbl.gov/floyd/ecn.html") 
also points to a few validation tests in ns-2 that use ECN;
when you are not sure of tcl syntax, the validation tests
in ns-2/tcl/test and examples in ns-2/tcl/ex should often help.
