Subject: Fixed a bug in the Tcl init script that did not have a "global env"
 and thus   setting the TCL_LIBRARY environment variable was not being set in
 the global   'env' array. Moved the varaibe 'tclPreInitScript' from
 respective tcl<plat>Init.c file. Added a routine 'TclSetPreInitScript()' to
 facilite setting the pre-init   script variable.   This file should only be
 included once in the entire   set of C source files for Tcl (by the
 respective platform initialization   C source file, tclUnixInit.c and
 tclWinInit.c) and thus the presence of   the routine, TclSetPreInitScript,
 below, should be harmless.
