[avr-gcc-list] avr-gcc toolchain: applying WINAVR patches for Linux box

[Chunhua Li]

I recently built avr-gcc on my Linux box, following the instructions on 
page http://www.nongnu.org/avr-libc/user-manual/install_tools.html. The 
building process is successful, but I have two questions to ask here.
1. How do I read the info page/man page, or other documents about 
avr-libc on linux builds?
2. I applied patches for gcc-4.2.0, but I don't know whether the 
patching is successful or not because I got a lot of "hunks" from the 
output of "patch -p0". See below.

I downloaded winavr patches from 
http://winavr.cvs.sourceforge.net/winavr/patches
and applied all patches for gcc-4.2.0. The patch files I used for 
gcc-4.2.0 are
gcc/4.2.0/10-gcc-4.2.0-c-incpath.patch
gcc/4.2.0/11-gcc-4.2.0-exec-prefix.patch
gcc/4.2.0/20-gcc-4.2.0-libiberty-Makefile.in.patch
gcc/4.2.0/30-gcc-4.2.0-binary-constants.patch
gcc/4.2.0/40-gcc-4.2.0-bug-28902.patch
gcc/4.2.0/41-gcc-4.2.0-bug-10768.patch
gcc/4.2.0/51-gcc-4.2.0-mega256-v2.patch

I wrote a script and and automated the building process and log all of 
outputs. From my log file I got the following information when I applied 
patch for gcc-4.2.0

You can see lots of "Hunks" here. I don't understand what the hunks mean 
here, but I want to know if the patches were applied successfully?

Thanks
