d79deccee9 Unfortunately lint uses c-style comments as directives and these get parsed
at the lexical analysis stage not at the syntax parsing stage. The upshot
is that:
	if (expr) {
		stmt1;
	}
	/* LINTED */
	stmt2;

stmt2 is the look-ahead token for the parser to choose between and if-then-else
statement as opposed to an if-then statement. Unfortunately the side effect
is that the LINTED directive gets reset before stmt2 gets parsed. We fix this,
by remembering the the linted directive during the if statement parsing and
restoring it at the appropriate time.

e79f03e595 Fix problems with LINTED comment:
if (a) b;
	/*LINTED*/
	c;

	if (a) { b; }
	/*LINTED*/
	c;

	do { b; }
	/*LINTED*/
	while (c);

Produced warnings for c.

bf7d5c8de3 Add -d option, so lint can be used safely when we're not building "in
place" (e.g., when DESTDIR is set).  This causes the lint driver to
pass -nostdinc -idirafter <dir> to cpp, causing it to ignore
/usr/include and look somewhere else instead..

81f0721bbe * accept the file name '-' to indicate that standard input is to be

46b90748f5 * Ignore the size of integer arguments when trying to automatically
convert them to pointers.  If they're zero, they're converted (to
  NULL pointers) regardless of size.  If they're non-zero, they can't
  be converted (without a cast).  This matches the behavior of other
  version of lint, e.g. the lints on Digital UNIX and HP-UX.

* recognize that pointers to identical unnamed and untyped structs,
  unions, and enums are, in fact, identical.  This is done by tagging
  each of unnamed and untyped structure, union and enum with a unique
  position of creation, which is used as a unique identifier that
  when determine whether or not a pair of structures, unions, or enums
  are identical.

  fixes the problem for the couple of cases where this is a problem
  in our tree.

5888f3bb16 LINTED and CONSTCOND are now valid up to the next end of a
global or local declaration/definition/statement. Originally they were
valid on the current and next line, which made it hard to suppress
warnings in constructs with more then one line.

LONGLONG can now be used to suppress errors or warnings in the next
declaration, definition or statement.

b95167a01a support asm statements and asm modifiers in declarations
asm statements consist of an asm keyword, an optional qualifier, a
left paren, a list of tokens up to and including the matching right
paren, and a semicolon.

asm modifiers consist of an asm keyword, an left paren, a string and a
right paren.

asm statements and modifiers have no semantic for lint(1), they exist only
to avoid complaints about them.
