Just one more question:
DEB_BUILD_MAINT_OPTIONS="future=+lfs" With that everyone (on a 32-bit platform) would e.g. get: dpkg-buildflags --get CPPFLAGS -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -Wdate-time -D_FORTIFY_SOURCE=2
Since many packages just use CFLAGS or CXXFLAGS (but not CPPFLAGS), wouldn't it make sense that dpkg-buildflags adds "-D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64" to those as well?
