-# With a modern GNU make(1) (highly recommended, that's what all the
-# developers use), all of the following configuration values can be
-# overridden at the command line. For example:
-# make CROSS=powerpc-linux- BB_SRC_DIR=$HOME/busybox PREFIX=/mnt/app
-
-# If you want a static binary, turn this on.
-DOSTATIC = false

-# Set the following to `true' to make a debuggable build.
-# Leave this set to `false' for production use.

-
-# This enables compiling with dmalloc ( http://dmalloc.com/ )
-# which is an excellent public domain mem leak and malloc problem
-# detector. To enable dmalloc, before running busybox you will
-# want to first set up your environment.
-# eg: `export DMALLOC_OPTIONS=debug=0x14f47d83,inter=100,log=logfile`
-# Do not enable this for production builds...

-
-# If you want large file summit support, turn this on.
-# This has no effect if you don't have a kernel with lfs
-# support, and a system with libc-2.1.3 or later.
-# Some of the programs that can benefit from lfs support
-# are dd, gzip, mount, tar, and mkfs_minix.
-# LFS allows you to use the above programs for files
-# larger than 2GB!
-DOLFS = false
