OK, this

#!/usr/bin/perl

my %new_values;
my @old_names;
my @old_values;
while (<>)
{
if (m/^\+#define\s+(\S+)\s+(\S+)\s+.*$/) {
$new_values{$1}=$2;
}
if (m/^\-#define\s+(\S+)\s+(\S+)\s+.*$/) {
push @old_names, $1;
push @old_values, $2;
}
}

for (my $i = 0; $i <= $#old_values; $i++) {
if (oct($new_values{$old_names[$i]}) != oct($old_values[$i])) {
print "Changed: $old_names[$i] $old_values[$i] " .
" to $new_values{$old_names[$i]}\n";
}
}

Shows that the only numbers changed are
MADV_REMOVE
MADV_DONTFORK
MADV_DOFORK

As was intended.
OK now?
