Subject: possible code error at run_command.c
Message-ID: <1976ea660912202246k45732bf2p111bbeb78047693e@mail.gmail.com>

int start_command(struct child_process *cmd)
{
	int need_in, need_out, need_err;
	int fdin[2], fdout[2], fderr[2];
	int failed_errno = failed_errno;

I have not found failed_errno as global variable.
failed_errno = failed_errno means nothing.

It is possible coding error and should be
int failed_errno= 0 or
failed_errno=errno.
