Tcl_PutEnv sets an environment variable. The information is
    passed in a single string of the form
    “NAME=value”. This procedure is intended
    to be a stand-in for the UNIX putenv system call. All Tcl-based
    applications using putenv should redefine it to Tcl_PutEnv so
    that they will interface properly to the Tcl runtime.
