Buffered IO curiosity effects non-CYGWIN programs.

["Ed Bradford" <egb at us dot ibm dot com>]

There were no replys to my question about buffered IO.

Write a 14 line program reading lines from stdin and printing them to
stdout. Compile with Microsoft CL.exe. Run the program from bash and it
runs as if buffering were turned on. It doesn't recognize the console as an
interactive output requiring immediate flushing. Run the very same program
from cmd.exe and it works correctly.

This is a bug in something because it effects programs that are not
compiled with CYGWIN. Has anyone seen this problem and is there any type of
resolution?

Thank you.

#include <windows.h>
#include <stdio.h>
main()
{
    char buf[128];

    while(fgets(buf,sizeof(buf),stdin)) {
        buf[127] = 0;
        printf("%s\n",buf);
        if(buf[0] == 'q')
            break;
    }
    return 0;
}
