* resolve file resolution conflicts between lwip and libcoap in favor of lwip by rearranging the makefile * cover the config.h of a configured base libcoap with the local one using the deprecated -I- gcc switch * enable etharp (no idea why it wouldn't work ootb, the complete server.c lwip-contrib copy needs to be reviewed) * disable optimizations for easier debugging, enable -g3 for macro expansions
