+Supported C language subset:
+
+ - Expressions:
+
+ * binary operators, by decreasing priority order: '*' '/' '%',
+ '+' '-', '>>' '<<', '<' '<=' '>' '>=', '==' '!=', '&',
+ '^', '|', '=', '&&', '||'.
+
+ * '&&' and '||' have the same semantics as C : left to right
+ evaluation and early exit.
+
+ * Parenthesis are supported.
+
+ * Comma operator is supported.
+
+ * Trinary operator (?:) is not supported.
+
+ * Unary operators: '&', '*' (pointer indirection), '-'
+ (negation), '+', '!', '~', '++' and '--'.
+
+ * Pointer indirection ('*') is supported.
+
+ * Square brackets can be used for pointer arithmetic.
+
+ * '=' and <op>= are supported.
+
+ * Function calls are supported with standard Linux calling
+ convention. Function pointers are supported.
+ Functions can be used before being declared.
+
+ - sizeof() is not supported.
+
+ - Types:
+ + int, short, char, float, double
+ + pointers
+ + variables can be initialized in declarations.
+ + Only ANSI-style function declarations are supported.
+ - "..." is not supported.
+ - short is not supported
+ - const is not supported
+ - arrays are not supported
+ - long doubles are not supported
+ - structs are not supported
+
+ - Unknown functions and variables are bound at compile time by calling
+ back to the caller. For the 'acc' command-line tool unknown functions
+ and variables are looked up using dlsym, to allow using many libc
+ functions and variables.
+
+ - Instructions: blocks ('{' '}') are supported as in C. 'if' and
+ 'else' can be used for tests. The 'while' and 'for' C constructs
+ are supported for loops. 'break' can be used to exit
+ loops. 'return' is used for the return value of a function.
+
+ - switch / case is not supported.
+ - goto and labels are not supported.
+ - continue is not supported.
+
+ - Identifiers are parsed the same way as C. Local variables are
+ handled, but there is no local name space (not a problem if
+ different names are used for local and global variables).
+
+ - Numbers can be entered in decimal, hexadecimal ('0x' or '0X'
+ prefix), or octal ('0' prefix).
+
+ - Float and double constants are supported.
+
+ - '#define' is supported without function like arguments. No macro
+ recursion is tolerated. Other preprocessor directives are
+ ignored.
+
+ - C Strings and C character constants are supported. All ANSI C
+ character escapes are supported.
+
+ - Both C comments ( /* */ ) and C++ comments ( // ... end-of-line ) are
+ supported.
+
+ - Some syntax errors are reported, others may cause a crash.
+
+ - Memory: the code, data, and symbol sizes are limited to 100KB
+ (it can be changed in the source code).
