-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 are supported.
-
-        * '=' 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 supported
-        - const is not supported
-        - signed and unsigned are not supported.
-        - arrays are supported
-        - long doubles are not supported
-        - structs and unions are supported
-        - typedef is supported
-        - explicit storage class specifiers are not supported: register, auto, static, extern
-
-    - 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.
-    - Macro recursion is allowed.
-    - Self-referential macros are handled as in gcc.
-    - '#pragma' is supported. The pragma text is passed to a callback function,
-       and is used to implement meta-information.
-    - 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).
