Overloaded functions

[jgannon]

In my header file, I have the following function prototypes:

int abs(int);
float abs(float);

In my source file, I have the following functions:

int abs(int x)
{
  if(x>=0)
    return x;
  else
    return -x;
}

float abs(float x)
{
  if(x>=0)
    return x;
  else
    return -x;
}

I also have a whole bunch of other overloaded functions. (I know this isn't the best example, but it's short.) However, when I compile it, I get a lot of "type mismatch in redeclaration of 'abs'" and "redefinition of 'abs'" errors. Does the C18 compiler not support overloading, or am I doing something wrong that I'm overlooking?
