Thread: warning message

What does the warning :
Cannot create pre-compiled header: code in header
mean and how do I stop this warning from occuring.

T

by the way its the Borland turbo c++ 4.5 Compiler

The code doesn't seem to matter:

It is part of a larger program. but this gives the exact same message.

/* Write this in the header file */
void call_function( void );


void call_function( void)
{
/* Does nothing */
}



/* and this in the main program */
#include "del_head.h"

int main()
{
call_function();
return 1;
}
