cygwin 1.7 message queues can't open more than 1 queue?

[Linh Phan]

Hi,

 I downloaded cygwin 1.7 to use message queues but unfortunately, the 
message queues only allows me to open
1 message queue.  If I try to open a second one, it fails with 
"Permission denied".  Below is the test I used:

#include <stdio.h>
#include <mqueue.h>
#include <fcntl.h>
main()
{
 int flags = O_RDWR | O_NONBLOCK | O_CREAT | O_EXCL;
 struct mq_attr attr;
 char queue[33];
 char *e;
 mode_t mode = strtoul("644", &e, 8);
 mqd_t mqd;

 memset((void *) &attr, 0, sizeof(struct mq_attr));
 attr.mq_maxmsg = (long) 10;
 attr.mq_msgsize = (long) 24;

 strcpy(queue, "/queue0");
 mq_unlink(queue);
 mqd = mq_open(queue, flags, mode, &attr);
 strcpy(queue, "/queue1");
 mq_unlink(queue);
 mqd = mq_open(queue, flags, mode, &attr); // ALWAYS FAIL HERE WITH 
"Permission denied"
 perror("mq_open");
}

Does anyone know what I did wrong?

Thank you,

Linh
