ANSI C and function overloading [duplicate]

Question

function overloading in C

ANSI C doesn't permit function overloading (I don't sure about C99).

for example:

char  max(char  x, char  y);
short max(short x, short y);
int   max(int   x, int   y);
float max(float x, float y);

is not a valid ANSI C source code.

Which technique (or idea) should be used for function overloading problem in ANSI C?

Note:

An answer is renaming the functions, but which pattern should be used for renaming, that function names remain 'good function name'?

for example:

char  max1(char  x, char  y);
short max2(short x, short y);
int   max3(int   x, int   y);
float max4(float x, float y);

is not a good naming for max function name.

Answer 1

Using the data type to be evaluated in the function name, for example

char  max_char(char  x, char  y);
short max_short(short x, short y);
int   max_int(int   x, int   y);
float max_float(float x, float y);
