Changing existing functions to ANSI style doens't break ABI.

But changing functions to ANSI style makes examination by "gcc -pendantic"
impossible. This is the problem, since number of library functions 
continuously increase.

BTW, Ted lemon suggest about adding compiler option which warns
K&R incompatible function. (without K&R style function definition 
and gcc -pedantic)
If that option exists, we do not need gcc -pedantic hack.
