* src/machine.h: Remove, leaving its contents in...
* src/system.h: here.
Include stdio.h.
Adjust all dependencies on stdio.h and machine.h.
* src/getargs.h: New file.
Let all `extern' declarations about getargs.c be replaced with
inclusion of `getargs.h'.
* src/Makefile.am (noinst_HEADERS): Adjust.
* tests/calc.m4 (yyin): Be initialized in main, not on the global
scope.
(yyerror): Returns void, not int.
* doc/bison.texinfo: Formatting changes.
(safegetc): New function to deal with EOF gracefully.
(literalchar); new function to deal with reading \ escapes.
(lex): Use literalchar.
(lex): Implemented "..." tokens.
(literalchar, lex, parse_percent_token): Made tokenbuffer
always contain the token. This includes growing the token
buffer while reading an integer.
(parse_percent_token): Replaced if-else statement with percent_table.
(parse_percent_token): Added % declarations as another
way to specify the flags -n, -l, and -r. Also added hooks for
-d, -k, -y, -v, -t, -p, -b, -o, but implementation requires
major changes to files.c.
(lex) Retain in the incoming stream a character following
an incorrect '/'.
(skip_white_space, lex): Revised most error messages
and changed fatal to warn to avoid aborting.
(percent_table): Added %thong declarations.
