It's a standard snippet used in the rules files of many packages in the Debian archive :) Recently it has started to gradually disappear for two reasons: 1. dpkg-buildpackage now examines DEB_BUILD_OPTIONS by itself and sets the appropriate CFLAGS and LDFLAGS (it also checks for "nostrip"). Still, this is far from perfect, since a package may not necessarily be built using dpkg-buildpackage - e.g. during testing the maintainer may sometimes run "debian/rules clean", "debian/rules build", etc. by hand to see how it goes. 2. More recently, dpkg-dev 1.15.7 introduced the dpkg-buildflags tool which is perfect for this task :) You may take a look at the rules files for the mbuffer or timelimit packages to see how it's used. Hope that helps :) G'luck, Peter -- Peter Pentchev roam@ringlet.net roam@FreeBSD.org peter@packetscale.com PGP key: http://people.FreeBSD.org/~roam/roam.key.asc Key fingerprint FDBA FD79 C26F 3C51 C95E DF9E ED18 B68D 1619 4553 I am the meaning of this sentence.
