This c code:
// begin ok.c
int bar(int a, int b, int c)
{
//if ((b = c) && (a == 0))
if (b = c)
{
return 0;
}
return 1;
}
// end ok.c
When compiled with
gcc -Wall -c ok.c
issues this warning:
ok.c: In function `bar':
ok.c:5: warning: suggest parentheses around assignment used as truth value
That is what I expect.
This code, however does not issue the warning:
// begin bad.c
int bar(int a, int b, int c)
{
if ((b = c) && (a == 0))
{
return 0;
}
return 1;
}
// end bad.c
gcc -Wall -c bad.c
(no output)

------- Comment #1 from manu at gcc dot gnu dot org 2010-02-21 00:21 -------
Confirmed in GCC 4.5
This whole business with the parenthesis to avoid warning in this case always
seemed fishy to me.
