M4 isn't really a problem here.  It is sed which does the substitution, 
and it does seem to have problems with embedded newlines.

Newer versions of autoconf seem to have an AC_SUBST_FILE() command, 
where the value of the env variable is a file, which gets substituted. 
Maybe this would be be useful?

(of course, being able to use a single line subst would be more convenient).
