Your advice did solve the problem, thanks!  I wonder which specific entry in the
changelog did it...

The unwillignness to show any text until it finds a newline seems it could be a
cygwin issue.  Taking the following code:

#ifndef __CYGWIN__
#define SLEEP _sleep(2000)
#else
#define SLEEP sleep(2)
#endif
#include <stdio.h>
#include <stdlib.h>
int main() {
 int i;
 while(1) {
  for(i = 0; i < 5; i++) {
   printf("%c", 'a'+i);
   SLEEP;
  }
  SLEEP;
  printf("\n");
 }
}

When built in visual C++, it will show 'a', 'b', 'c' etc every 2 seconds.  When
built in cygwin with gcc, it will show 'abcde' every 10 seconds.  The latter
happens whether I run it from a bash console or windows console.

I'll start a new thread for this if noone off-handedly has the answer...
