Here gcc gives the following message:
test_mq.c:186: warning: suggest parentheses around assignment used as truth
value
Which should be the sign that something is not correct,
a=b == c is interpreted by the compiler as a=(b == c), whereas you would
like
(a = b) == c.
So, add the parentheses, and everything should work fine.
However, I do not understand what your program is supposed to do, here
it dies without printing anything.
