Just call them, like this:
tg@zigo:~/Xl/linux-2.6-3.2~rc7 $ fgrep -A 3 "define strcpy" arch/m68k/include/asm/string.h #define strcpy(d, s) (__builtin_constant_p(s) && \ __builtin_strlen(s) <= 32 ? \ __builtin_strcpy(d, s) : \ __kernel_strcpy(d, s))
Of course, the parameters when to call which may differ. (The choice about being a hosted environment is not just about having libc-like functions available.)
