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.
