I've not tried it but it should compile:

#include <stdio.h>
#define HOW_MUCH_I_M_STUPID	MAX_INT /* or INT_MAX ?*/

static char message[]=
"This is H M I S - (c) 1998 by Federico Spinazzi\n\
         o a m t\n\
         w c   u\n\
           h   p\n\
               i\n\
               d\n"

int main()
{
int hmis;

	fprintf(stdout,"%s",message);

	fprintf(stdout, "Hit a key to disconnect brain from mouth.\n");
	fflush(stdout);
	getch();

	for(hmis=HOW_MUCH_I_M_STUPID; hmis; hmis--) {
		fprintf(stdout, "Hey, do you know how much I'm stupid
?\n");
		fflush(stdout);
	}
	fprintf(stderr, "Oh yeaH !!\n");
	fflush(stderr);
	exit(0);
} 

compile with -Wall -O3 at least. 
Redirect stdout to a file for speed.
DJGPP will take care to reconnect brain to mouth, so don't worry about it.

When DJGPP'll have 64-bit words, you'll be alble to loop it 22222222222222
times in a single for() (using double will slow CPU with no coprocessor).
In the mean time you can nest loop one into each other.

(Future releases of H M I S will include a multi-threading version)

PS: I'm sorry, really.
