7d8b9145a5 Ignore restrict in the contexts where const and volatile is allowed. 
No validation for the use (e.g. that it is used on a pointer), but
enough to not stop valid C99 programs.

8a89a3dc54 Check value range of ULONG and UQUAD values. On 32 bit platforms like 
i386 "unsigned long x = 0x800000000UL;" passed lint and gcc complains
(rightfully). Validate quad as well to allow using a potentially larger
type to store the value.

3457928c2a Add Picky flag; this produces more warnings: 
1. long a; int i; a = i * i;
   suggests casting i to long, so that we gain precision in the multiplication.
2. warns about magnitude comparisons in enums.
3. warns about possible sign extension issues when integer types become widened.

d4d6980a4b Add a check for 'continue' inside a 'do ... while (0)' loop. 
'continue' has the same effect as 'break' - as that probably isn't
what the writer had in mind!
