It may be the simplest way, although some may consider it to be untidy.
Is it not possible to open(), or to popen(), an output stream in the
parent process, then bind it to STDERR_FILENO with dup2(), *before*
calling ShellExecuteW()? That's the normal (programmatic) way to set up
I/O redirection, and it is, after all, what the shell itself most likely
does, when it processes "2> FILE".
