 *   Naming conventions
 *	- Symbols are prefixed with MSVCRT_ if they conflict
 *        with libc symbols
 *      - Internal symbolx are usually prefixed by msvcrt_.
 *      - Exported symbols that are not present in the public
 *        headers are usually kept the same as the original.
 *   Other conventions
 *      - To avoid conflicts with the standard C library,
 *        no msvcrt headers are included in the implementation.
 *      - Instead, symbols are duplicated here, prefixed with 
 *        MSVCRT_, as explained above.
 *      - To avoid inconsistencies, a test for each symbol is
 *        added into tests/headers.c. Please always add a
 *        corresponding test when you add a new symbol!
