Thanks for telling me there is no portable flag for doing so. I am now using AC_SUBST() to set the value of STREAM and append ` $(STREAM)>/dev/null' to every make command. If the user configure with --enable-verbose-compiler, then STREAM will be set to 0, otherwise STREAM will be set to 2. This keeps the flexibility. Does it sound reasonable?
I'm not sure if an output redirection on stdin is portable. But I think given the way you are going about this you could easily set a Makefile variable to the full redirection (or none), i.e. lose the >/dev/null and instead make STREAM be either '2>/dev/null' or the empty string ''?
