Re: [avr-gcc-list] avr-gcc build errors

[Neil Davey]

Hi Mark,
I had similar problems when I first tried to compile gcc... (same error
message also..)

I then followed the procedure detailed here: (pointed out to me by 
someone on the list)
http://www.nongnu.org/avr-libc/user-manual/install_tools.html

using the latest versions, built without any problems after that...

Regards
Neil Davey
