--- Comment #1 from torhu at yahoo.com ---
Since batch files are not executables, but interpreted by cmd.exe, you need to
use spawnShell instead.

Or are you suggesting that files with extensions in PATHEXT should be treated
in a similar way to Linux shell scripts with shebang lines in them? It's a bit
messy to implement that. The Windows ShellExecuteW function will run
non-executables, but it doesn't allow you to set environment variables. So it's
not a generic replacement for CreateProcessW.
