If it's a one-off thing, you can always do

    (let ((process-environment (cons "LANG=en" process-environemnt)))
      (process-launching-stuff))

Now, suppose you want to automate this within a certain project.  Then
you want to arrange for

    (setq-local process-environment (cons "LANG=en" process-environemnt))

to be called in every buffer of the project (there are packages out
there to help doing this).  This mostly works, but some commands get
confused when `process-environment' has a buffer-local value.  The patch
is a fix for `compile'.
