Here's what I did to get around this.  In src/lib/tklua.c, change the
following line:

  Tcl_Interp *interp = Tcl_CreateInterp();


  Tcl_Interp *interp;
#ifdef _WIN32
  interp = Tcl_CreateInterp();

Please note that this is something of a hack, since calling
Tcl_FindExecutable with a NULL argument isn't strictly legitimate (and
will blow up on UNIX).  However, on Windows it will work and will fix
the problem you mentioned.

This seems to be needed on Windows as well as cygwin.  That's why I used
#ifdef _WIN32.

For more info see the "Tcl/Tk on Windows FAQ" at (item C-10) and the Tcl source
