Parse error help please

[lbyram]

#include <stdio.h>
#define MAX 25

int read_array(double ar[], int limit);
void show_array(const double ar[], int n);
double mean(const double ar[], int n);
int main(void)
{
  double data[MAX];
  int size;
  double average;
  size = read_array(data, MAX);
  if (size == 0)
       printf("No data. Bye.\n");
  else
  {
       printf("The following numbers were entered:\n\n");
       show_array(data, size);
       printf("\nThe average of these values is %.2f.\n",
            mean(data, size));
  }
  return 0;
}

void show_array(const double ar[], int n);

This line consistently gives me a parse error that says Parse Error, expecting `')'' or `',''. I surfed the Web and the FAQ's here, and they point to a missing close parens in the statement, but it is identical to the previous statement. Any help would be appreciated.

Works for me too under Turbo C 1.0 and Borland C 5.5
