Thanks for your job Ake! I have some technikal problems. I'm using at now Debian Etch (stable 9.3) architecture amd64 and i386. gdb and binutils installed are slightly different version and target, also I have use binutils-avr but those are have different names. What would happen if I install your modified versions over them? I still need those version and architecture and I have plans for armeabi or eabihf. What I can do to keep my packages consistent? You propose SDCC 3.6.0 but I have use 3.6.9...
