// Check UNIX conformance for cc/c89/c99
// When c99 encounters a compilation error that causes an object file not to be
// created, it shall write a diagnostic to standard error and continue to
// compile other source code operands, but it shall not perform the link phase
// and it shall return a non-zero exit status.

// When given multiple .c files to compile, clang compiles them in order until
// it hits an error, at which point it stops.
