I have no fundamental object to this one, but
the 80 column use is unnecessary and should be
coalesced before it can be applied.

Perhaps:

# warn about #if 1
		if ($line =~ /^.\s*\#\s*if\s+1\b/) {
			WARN("IF_1",
			     "Consider removing the #if 1 and its #endif\n" .  $herecurr);
 		}

This one has I think too many existing uses of
things like "return -1;"

$ git grep -P "return\s*\-\d+\s*;" | wc -l
9929

How many of these are actually appropriate?

Also, no space is required between return and -1
by c90 and this should use $Int so it should be:

	if ($line =~ /\breturn\s*\-\$Int\s*;/) {

etc...
