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

[Eshwaran Vijaya Kumar]

Hi Bernard,
  Thanks for your mail. Just a note of clarification. How did you get
the patches from WinAVR 20080610? I only have linux. Do i have to use
wine to extract the patches from the installer? Or can i use the
patches from the CVS for the appropriate versions of bin utils and
GCC.
Thanks a ton again.
Regards
Eshwaran
