◆ c_file_name

const char* c_file_name
extern

Referenced by collect_execute(), and main().

◆ may_unlink_output_file

bool may_unlink_output_file
extern
Whether we may unlink the output file, which should be set as soon as we know we have successfully produced it. This is typically useful to prevent blindly attempting to unlink a read-only output that the target linker would leave untouched.
