returns EOF. Initialize C to zero before loop; in loop if C is EOF, set
optarg from ARGV[optind++], else call getopt_long.
(decode_env_switches): Use variable_expand instead of
allocated_variable_expand. Allocate a fresh buffer to copy split words
into; scan characters by hand to break words and debackslashify.
(shell_quote): New function.
(define_makeflags): Allocate doubled space for switch args, and command
variable names and values; use shell_quote to quote those things.
(command_variables): New type and variable.
(decode_switches, decode_env_switches): After making a variable definition,
record the struct variable pointer in the command_variables chain.
(define_makeflags): If ALL, write variable definitions for
command_variables.
(goals, lastgoal): New static variables (moved from auto in main).
(main): Don't process OTHER_ARGS at all.
Don't set variable MAKEOVERRIDES at all; define MAKE to just $(MAKE_COMMAND).
(init_switches): Prepend a - (return in order) instead of a + (require order).
(decode_switches): Don't set OTHER_ARGS at all.
Grok '\0' return from getopt_long as non-option argument; try variable
definition and (if !ENV) enter goal targets here.
(decode_env_switches): Use allocated_variable_expand to store value.
Use find_next_token to simplify word-splitting loop.
Don't prepend a dash to uninterpreted value.
Instead, if split into only one word, try variable definition and failing
that prepend a dash to the word and pass it to decode_switches as a single arg.
cs_running on entry (meaning the commands actually just ran).
(update_file_1): Whenever we set FILE->update_status, call
notice_finished_file instead of just set_command_state.
(main) [__MSDOS__]: Look for \ or : to delimit last component of PROGRAM.
Don't frob ARGV[0] before setting MAKE_COMMAND variable.
(die): Change back to `directory_before_chdir' before dying.

(PATH_SEPARATOR_CHAR): New macro; differing defns for [__MSDOS__] and not.
[__MSDOS__] (dos_pid, dos_status, dos_bname, dos_bename, dos_batch_file):
New variables.
(reap_children) [__MSDOS__]: Don't call wait; just examine those vars.
(unblock_sigs) [__MSDOS__]: Do nothing.
(start_job_command) [__MSDOS__]: Use spawnvpe instead of vfork and exec.
(load_too_high) [__MSDOS__]: Always return true.
(search_path) [__MSDOS__]: Check for : or / in FILE to punt.
Use PATH_SEPARATOR_CHAR instead of ':'.
(construct_command_argv_internal) [__MSDOS__]: Wholly different values for
sh_chars and sh_cmds. Wholly new code to handle shell scripts.

(dir_contents_file_exists_p) [__MSDOS__]: Call it on FILENAME and process
the result instead of FILENAME itself.
(file_impossible_p) [__MSDOS__]: Likewise.

(default_suffix_rules) [__MSDOS__]: Use `y_tab.c' instead of `y.tab.c'.
(default_variables) [GCC_IS_NATIVE]: Set CC and CXX to `gcc', YACC to
`bison -y', and LEX to `flex'.
