src/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. src/w32.h (check_windows_init_file): Add prototype. src/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. src/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. src/lread.c (init_lread): Add comments to #ifdef's. nt/paths.h (PATH_LOADSEARCH, PATH_SITELOADSEARCH, PATH_EXEC) (PATH_DATA, PATH_DOC): Replace dummy directory names with directories relative to %emacs_dir%. (PATH_EXEC): Add lib-src/oo-spd/i386 and lib-src/oo/i386, to cater to the use case of running un-installed Emacs.
