compiler PROBLEM

prog.c:2:18: fatal error: conio.h: No such file or directory
#include<conio.h>
^
compilation terminated.

my code is running on my system but why is the codechef compiler showing this compilation error message when i m using C GCC(4.8.1)

 #include<conio.h> 

do not need in codechef program.

Program will easily run without using this header file.
