A just-in-time compiler for c minus

---

Features:

• One-pass compiler
• Hashtable based lexical analysis
• Top-down operator precedence parsing, LL(k)
• JIT on x86
• Interactive console
• Windows/Linux/MacOSX support
• No more than 1000 lines of code

Example:

    scan@ubuntu:~/TinyC$ make
    g++ -m32 -g pch.h
    g++ -MMD -m32     -g   -c -o main.o main.cpp
    g++ -MMD -m32     -g   -c -o pch.o pch.cpp
    g++  -o main main.o pch.o -MMD -m32     -g -ldl
    scan@ubuntu:~/TinyC$ ./main
    >>> 1+2*(3-5)

    >>> factorial(10)
    3628800
    >>> feb2(11)
    89
    >>> feb2(10)+feb2(9)
    89
    >>> int pow(int x, int y) { int r = 1; for (int i = 0; i < y; ++i) r = r * x; return r; }
    >>> pow(2, 10)
    1024
    >>> 32 * pow(2, 10)
