If you write functions that are named like the original ones, you may
get into problems with two points:
1) other functions from libc may use implementation specific
details and force to have both implementations probably
working against each other or detroying data structures.
2) If you use stdin/stdout/stderr there is a high chance to
force to hit point 1)

If you name it differently, you may include the system's stdio too, but
then you may not call any of your functions the same as they are called in
stdio.h
look at http://www.opengroup.org/onlinepubs/7908799/xsh/stdio.h.html
and see that there may be many problems.
