Make sure that the variable type holds all flags. An int holds 4 bytes (32bit) and a long holds 8 bytes (64bit). If you just have 8 flags, use a char, because that is stored as 1 byte. Especially in network scenarios such consideration are interesting.

Enums are not supported in Lite-C and they aren't flags. They are just constant names assigned to a numeric integer value. So if you have in C/C++ e.g.
Code:
enum { Apple, Orange, Banana, Melon } Fruit;

you could do something like that:
Code:
Fruit fruit = Apple;


Internally, they translate to constants like 0, 1 and 2. So, to emulate enums in Lite-C, you could do this, although it involves more writing:
Code:
#define Apple 1
#define Orange 3
#define Banana 5
#define Melon 7

typedef int Fruit;

Fruit fruit = Apple;

if (fruit == Melon)
   error("Shh you got to, shake it, shh shake it, shake it, got to shake it");
else
   if (fruit == Banana)
      error("(Shake it sugar) shake it like a Polaroid Picture");
