TCL users - bug in "exec" command

[Drew R Whitehouse]

	For any one using tcl on SG's machine - vfork isn't supported
properly. This breaks the exec command. The fix is simple, in
Tcl_ExecCmd() (tclCmdAH.c) replace the call to vfork woth fork. I use
-


    /*
     * Fork off the child process.
     */

#ifdef sgi
    pid = fork();
#else
    pid = vfork();
#endif
