No, it's not a problem with the compiler. When you remove the function name,
the code is still valid.

For example:

int main() {
   int a;
   a = (1,2,3,4);
   printf("%d\n", a);
}

ryan@avarice:~$ gcc t.c
ryan@avarice:~$ ./a.out
4

See 6.5.17 Comma operator of the C Standard for more information

help..

Hello All,

I am trying to compile the file with the following code. 

Originally it was:
if ((erc = pk_val(pline, pkt, mp, PKT_CLEAR, PK_LOCAL))
By accident I saved the file with the following code.
            if ((erc =  (pline, pkt, mp, PKT_CLEAR, PK_LOCAL))

By accident pk_val_call got deleted and when I complied the above code
using the options 
cc -c -g, it got compiled successfully. I tried removing  -g also. Even
then it gave success. Is this a problem with the compiler? Is there a
fix for this that I can use.
Appreciate your help.

Soujanya
