Yes, and it's because you are declaring your functions with default
return types.  This is a very bad; even unsanitary habit to get into, so
it's best you break it ASAP.  Here's code that doesn't give any
warnings, even with -Wall (which I strongly suggest you use).  The extra
spacing and formatting is my own; feel free to adopt this style or any
other you choose.  :)

// my c program
#include <stdio.h>
#include <conio.h>

int newFunction( int i );     // prototype

int main( void )
{
    int i = 5;
    clrscr( );
    printf( "blah blah" );
    newFunction( i );
    return 0;
}

int newFunction( int i )
{
    printf( " %d", i );
    return 0;
}
