5c2e510661 Prevent lint1 from coredumping on invalid c code such as: 
foo((sockaddr *(void *))0);

This fix is imperfect, because right now we just check the subtype
chains for NULL and we return to the caller when the loop ends, leaving
the upper layers to cope with the syntax error. Ideally we should:

	a.) return an error to the upper layer, or
	b.) not call the type analysis routines in the presence of a syntax
	    error.

That would require a significant re-write which would take much more time
than I have...

5cb75fd417 Now that we use cc -E, -U__GNUC__ to avoid gnu extensions. Nuke the

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.

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.
