I have finally got a chance to start porting some of our work utilities
to OS/2 using GCC 2.1  A lot of our programs are really simple command
line utilties used for manipulating data files.  Can someone tell
me what is wrong with this?  I compile and run it under gcc 2.1, no
errors in the compilation.  The system does not print any output until
I type in enough input first, or press ^Z, to end my input stream.

#include <stdio.h>
#include <stdlib.h>

main() {
	char buffer[100];

	printf("This is a test\n");
	scanf("%s", buffer);
	printf("Buffer = %s\n", buffer);
}

Is there an ioctl statement I need to use first? This is such a basic
program that I figure it MUST work.  Any ideas?
Thanks.

Insure that you set output buffering off.  I believe the call is 
setbuf(stdout,NULL) .
