christos 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.

christos 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.

cgd f9356d1960 implement (hack in) symbol (function and variable) renaming, so that
the function renaming tricks currently needed by libc can be tolerated
by lint.  This needs some cleanup, but it appears to work.

simultaneously, e.g. an enumerated bit-field.

cgd 06fa442b12 * 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.

* accept the file name '-' to indicate that standard input is to be
  used as lint1 input.  That involves having lint pass the '-' through
  to the cpp which preprocesses the lint1 input, and having lint1's
  scanner recognize a cpp filename "" as "{standard input}".

cgd e8685ee836 * Accept asm statements at any place where you could see a function or
variable declaration, in addition to within function & variable
  declarations and function bodies.  I think this comes close enough
  to what gcc does to be considered "correct enough."  Certainly, it
  fixes the problem for the couple of cases where this is a problem
  in our tree.

jpo 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.

jpo 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.
