Unable to modify argument with "const". 5. Handles a declaration without a type specifier, type modifier or memory area class specifier as the declaration of "int" type. 6.

Supports the __asm keyword. 10. Supports the single line comment (//). 11. Supports the following built-in functions. __EI __DI __segbase_n __segbase_f __segsize
