<pre>Test case:
Setup:
# echo "int main(void){return 0;}" > test.c
# clang -c -o test.o test.c
Now this just works fine:
# clang -std=c89 -o test test.o
But this outputs a warning:
# clang -ansi -o test test.o
clang-11: warning: argument unused during compilation: '-ansi'
[-Wunused-command-line-argument]
The man page describes -ansi as "Same as -std=c89."</pre>
