146 // BusyBox will, by default, malloc space for its buffers. This costs code
147 // size for the call to xmalloc. You can use the following feature to have
148 // them put on the stack. For some very small machines with limited stack
149 // space, this can be deadly. For most folks, this works just fine...
150 //#define BB_FEATURE_BUFFERS_GO_ON_STACK
151 // The third alternative for buffer allocation is to use BSS. This works

160 // feature, you _must_ have patched the kernel to include the devps patch that
161 // is included in the busybox/kernel-patches directory. You will also need to
