Re: [avr-gcc-list] A few basic doubts regarding installing AVR-GCC on Fedora 9

[Dave N6NZ]

WinAVR and the *nix releases are kept in close sync by Eric and Joerg. 
Most *nix users follow the "Bingo scripts" found in a sticky thread at 
avrfreaks.net in the gcc forum.  The Bingo scripts are reliable and 
incorporate all the patches.
