its value has been determined in a manner similar to C. However, this was not the case. This patch should fix the problem. PR: bin/34032 Submitted by: Alan Eldridge

Add a -E flag, similar to -e (overide variables from environment) except

1999-07-31T20:53:02Z

that -E only operates for a specified variable. Useful since the -e option will often pull-in many unwanted variable overrides (esp. in a make world situation). Uses include overriding BINOWN (which cannot be done by normal methods or through abuses of MAKEFLAGS) or likely for ports to honour CFLAGS (provided they're running on a system whose make(1) has this option).

Add :Q to quote variable expansion to all proper expansion of

1999-04-19T07:30:04Z

variables for recursive makes. This makes it less painful to cross build recent NetBSD kernels on FreeBSD. Obtained from: NetBSD
