Go into the source directory for emacs, and add a define to config.h
for MAINTAIN_ENVIRONMENT, do a make clean, followed by a make.  If
this is defined, emacs passes the entire environment to subprocesses.
You can also do (setenv "variable" "value") then from within emacs.
Note, the documentation for setenv is messed up....
