I can't reproduce with that exact command, but I can if I force Objective-C:

$ /usr/local/bin/gcc -fno-diagnostics-show-caret-ansi -pedantic-errors -S 
-m32 -o warn-nsstring.s
/private/var/root/gcc-git/gcc/testsuite/gcc.dg/warn-nsstring.c 
$ /usr/local/bin/gcc -x objective-c -fno-diagnostics-show-caret -c -ansi
-pedantic-errors -S  -m32 -o warn-nsstring.s
/private/var/root/gcc-git/gcc/testsuite/gcc.dg/warn-nsstring.c 
/private/var/root/gcc-git/gcc/testsuite/gcc.dg/warn-nsstring.c:4:1: error:
format string argument is not a string type
/private/var/root/gcc-git/gcc/testsuite/gcc.dg/warn-nsstring.c:5:1: error:
format string argument is not a string type
$

So, confirmed since the 2nd command errors.

A relatively simple fix is a new option OPT_Wformat_pedantic that is enabled by
default. Another option is to enable Wformat by default. That doesn't sound too
bad.
