   | Generally, there are two answers.

   | 1.  Compile emacs with the MAINTAIN_ENVIRONMENT variable set.  This

   And, if you don't have MAINTAIN_ENVIRONMENT turned on, you can use
   this code:

... [ elisp code removed ]

Merlyn,

Thanks very much for the effort, but that doesn't work.  Perhaps it is
because i do not have MAINTAIN_ENVIRONMENT defined, but i had written
a routine just like the one you posted before i posted my original
article.  Change process-environment by hand does not help.  All
subshells started after the process-environment variable is set DO NOT
reflect the changed environment.  To see this do:

	M-x edit-options
	Change process-environment to whatever you like,
	M-x shell
	shell prompt -> printenv

the environment printed out in the subshell is entirely wrong.  
looks like a bug in gnuemacs dist-18.53.  

Please tell me i'm wrong.

p.s.  in the meantime i have found a hack/fix.  i changed a local
version of the compile library to invoke the 'env' program distributed
with gnuemacs dist-18.53.  so i say:

	M-x compile
	Compile command: make install

and my hacked compile.el invokes the compilation as:
	env PATH=whatever make install
