There is a difference in the behaviour for the WIN32 port. In other
platforms execl() is called from "src/bin/pg_ctl/pc_ctl" with the full path
("/bin/sh"), but for WIN32 the function CreateProcessAsUser() calls the CMD
command without a path, and this function has a search logic of its own [1].

If even this difference out is of any value I can propose a patch.
