It should. The ELisp manual says that, see the node "Subprocess Creation". This isn't specific to call-process, that variable is used by all the functions that create subprocesses. > Using '(setenv "PATH" "...")' does not have the expected effect for > 'call-process'.

The changes to the environment variables only affect the environment passed to subprocesses, they don't affect the environment of the Emacs process itself.
