What commands did you (or your build system) run? What was the output?

In fact, this works just fine for me:

$ cd /tmp
$ touch foo.c bar.c baz.c
$ mkdir b
$ cd b
$ clang -c -Wall -pedantic -Wextra ../foo.c ../bar.c ../baz.c
../foo.c:1:1: warning: ISO C requires a translation unit to contain at
least one declaration [-Wempty-translation-unit]
1 warning generated.
../bar.c:1:1: warning: ISO C requires a translation unit to contain at
least one declaration [-Wempty-translation-unit]
1 warning generated.
../baz.c:1:1: warning: ISO C requires a translation unit to contain at
least one declaration [-Wempty-translation-unit]
1 warning generated.
$ ls -l *.o
