I have included the function from tools.c PLUS the constant missing. Now the 
error message gets even stranger. This is just not my day. Any help welcome. 

#include "stdlib.h"
#include <stdio.h>


#define FINDCMD "/usr/bin/find %s -follow -type d -name '%s' 2> 
/dev/null;echo"
#define MAXPARSEBUFFER KILOBYTE(10)

char *readline(FILE *f)
{
  static char buffer[MAXPARSEBUFFER];
  if (fgets(buffer, sizeof(buffer), f) > 0) {
     int l = strlen(buffer) - 1;
     if (l >= 0 && buffer[l] == '\n')
        buffer[l] = 0;
     return buffer;
     }
  return NULL;
}


int main(){

        char *cmd = NULL;
        asprintf(&cmd, FINDCMD, "/video", "*.rec");
        FILE *p = popen(cmd, "r");

        char *s;
        while ((s = readline(p)) != NULL) {
           sprintf(stderr, "%s", *s);
        }
        pclose(p);


//      system(cmd);
        return 0;
}
