That is not a good reason not to warn:
[hjl@gnu-mic-2 gcc]$ cat /tmp/w.c
static const int foo[0x1000];
[hjl@gnu-mic-2 gcc]$ gcc -Wall -S /tmp/w.c
[hjl@gnu-mic-2 gcc]$ cat w.s
.file "w.c"
.local foo
.comm foo,16384,32
.ident "GCC: (GNU) 4.8.2 20140115 (Red Hat 4.8.2-11)"
.section .note.GNU-stack,"",@progbits
[hjl@gnu-mic-2 gcc]$
If we want to avoid rcs_id warning, we can check it explicitly and
not to warn it.
