Both POSIX and glibc use 'restrict' in wcstombs().
Let's use it here too.

.../glibc$ grep_glibc_prototype wcstombs
stdlib/stdlib.h:937:
extern size_t wcstombs (char *__restrict __s,
			const wchar_t *__restrict __pwcs, size_t __n)
     __THROW
  __attr_access ((__write_only__, 1, 3)) __attr_access ((__read_only__, 2));
.../glibc$
