+       Fix startup warnings about ../site-lisp on MS-Windows.  (Bug#11959)
+       * w32.c (init_environment): Change the default values of many
+       environment variables in dflt_envvars[] to NULL, to avoid pushing
+       them into environment when they were not already defined.  Remove
+       the code that deletes site-lisp subdirectories from the default
+       value of EMACSLOADPATH, as it is no longer needed.
+       (check_windows_init_file): Now external, not static.  Use
+       Vload_path as is, without adding anything, as this function is now
+       called when Vload_path is already set up.
+
+       * w32.h (check_windows_init_file): Add prototype.
+
+       * emacs.c (init_cmdargs) [WINDOWSNT]: When running from the build
+       directory, ignore the /*/i386/ tail in Vinvocation_directory, for
+       compatibility with Posix platforms.
+       (main): Move the call to check_windows_init_file to here from
+       w32.c.
+       (decode_env_path) [WINDOWSNT]: Expand the %emacs_dir%/ prefix, if
+       any, in the DEFALT argument into the root of the Emacs build or
+       installation tree, as appropriate.
+
+       * callproc.c (init_callproc_1): Call decode_env_path instead of
+       doing its equivalent by hand.
+       (init_callproc): Replace DOS_NT condition with MSDOS, thus letting
+       the code that sets Vexec_path run on MS-Windows.
+
+       * lread.c (init_lread): Add comments to #ifdef's.
+
        * msdos.c (dos_set_window_size, IT_update_begin)
        (IT_frame_up_to_date, IT_set_frame_parameters): Use FVAR and WVAR
        instead of direct references.
