Yes, very likely this would break many things. GNUMAKEFLAGS is really intended for options which change the behavior of GNU Make only in superficial ways. But, you don't want to set them in MAKEFLAGS in your environment in case you run non-GNU Make sometimes as well. One canonical example of such an option is --no-print-directory. The docs do mention this, at least: > It’s best to use GNUMAKEFLAGS only with flags which won’t materially > change the behavior of your makefiles. If your makefiles require GNU > Make anyway then simply use MAKEFLAGS. Flags such as ‘--no-print- > directory’ or ‘--output-sync’ may be appropriate for GNUMAKEFLAGS. Agreed that the docs will need to be updated. In the paragraph prior to GNUMAKEFILES in the docs we are talking about putting MAKEFLAGS in the environment, and the author (:-)) mentally continued that context without making it clear.
