143 // BusyBox will, by default, malloc space for its buffers. This costs code
144 // size for the call to xmalloc. You can use the following feature to have
145 // them put on the stack. For some very small machines with limited stack
146 // space, this can be deadly. For most folks, this works just fine...
147 //#define BB_FEATURE_BUFFERS_GO_ON_STACK
148 // The third alternative for buffer allocation is to use BSS. This works
149 // beautifully for computers with a real MMU (and OS support), but wastes
150 // runtime RAM for uCLinux. This behavior was the only one available for
151 // BusyBox versions 0.48 and earlier.

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