I suggest to take another look at the use of type modifiers
in the semantic patch language. It seems that it matters occasionally
to specify them explicitly.
How do you think about to reuse a SmPL script like the following?
@find_unsigned@
typedef _Bool, bool, u8, u16, u32, u64;
{
unsigned,
unsigned char,
unsigned int,
unsigned short,
unsigned short int,
unsigned long,
unsigned long int,
unsigned long long,
unsigned long long int,
size_t,
_Bool,
bool,
u8,
u16,
u32,
u64
} var;

*var
