Re: [PATCH 2/5] gnu: Add avr-gcc.

can't find all of its headers and libraries since they aren't in /usr. Some background: avr-gcc was broken for a very long time, until Manolis, Ricardo, and I worked out the problems several months ago. I tested avr-gcc by successfully compiling the various KADE miniArcade firmwares using

Re: [PATCH 2/5] gnu: Add avr-gcc.

bleUSB() { return obj; } Should that have worked as-is? Also, why is avr-gcc also setting native-search-paths (even though it's a cross compiler)? Doesn't seem to make a difference and is also rather strange... What does the search-paths form do? Does it set environment variables in the profile as well?
