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

153 // BusyBox versions 0.48 and earlier.

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