Re: [avr-gcc-list] Trouble compiling avr-gcc > 4.4.4 on Mac OS X Leopard with gcc-4.2

Hi Bingo,

Sometimes even just a small grain of dust is enough to lead you on the right 
track. ;)

I've tried so many different things so far, so it would be silly not to try 
these two things. ;)

Perhaps diffing Makefile.in between 4.4.4 and 4.5.0 would help, but right now 
I'm really too sleepy (lack of distcc) for having a go at it. ;)

I even tried getting Yagarto to compile 4.6.1, but it does not seem to work on 
PowerPC; I've heard that it builds fine on intel Macs.

Uhm, last time I compiled avrdude, I think I got libusb support working; I may 
be wrong, but that's how I remember it, and I guess I wouldn't be able to use 
it for much without libusb, since I use AVRISPmkII myself.

I've already made a function, which removes any path that leads to avr-gcc and 
the other avr-tools, so I'm past that point. :)

gcc-4.4.4 and earlier builds fine on my machine with exactly the same script, 
so the basic trouble is out of the way already.
