==known bugs==
when SYSTEM.LSH(s, n) where s is SET c compiler generates an error: "error: duplicate 'unsigned'", that's because SET is defined as unsigned already and LSH is defined in SYSTEM.h as ((t)((unsigned t)(x)<<(n))), that's why currently it's not possible to make SYSTEM.LSH with type SET.
I don't want to prohibit it at the parser level because C backend is only one of possible backends.
The solution currently is to cast set type to longint before lsh-ing it. And then casting it back to set if necessary.
