* tests/unixInit.test:
* unix/tclUnixInit.c (TclpInitLibraryPath):
* win/tclWinInit.c (TclpInitLibraryPath): Several entries in
the library path ($tcl_libPath) are determined relative to the
absolute path of the executable. When the executable is
installed in or near the root directory of the file system,
relative pathnames were being incorrectly generated, and in
the worst case, memory access violations were crashing the program.
