If I start of with a program such as this:

/**test.c***********/

void main(void)
{
  int i;
  for (i=0; i<5; i++); /* do-nothing */
}

/*******************/

and compile it like this:

	gcc test.c -o without

Then I add one function (to reposition cursor), like this:

/**test.c***********/

#include <conio.h>

void main(void)
{
  int i;

  for (i=0; i<5; i++); /* do-nothing */
  gotoxy(1,1);
}

/*******************/

and use the following compile sequence,

	gcc test.c -o with

Now, it I compare the file sizes of with.exe and without.exe,

 1-04-97  22:46         100,205  with.exe
 1-04-97  22:47          61,446  without.exe


POINT!!!: Why does the addition of gotoxy(1,1) add 40k of code the the
size of the executable??  In assembler such an addition would be about 10
bytes!

How can I stop the whole conio (I assume) library from being linked in????

Thankyou.

Matthew
