[avr-gcc-list] compiling avr-gcc in osx

[John Butera]

I am trying to build the avr tool chain in osx 10.2.6, but I am having  
difficulty compiling gcc.

For the most part, I am following the instructions listed in the  
avr-libc manual..
http://savannah.nongnu.org/download/avr-libc/doc/avr-libc-user-manual/ 
install_tools.html

I downloaded the source tarballs from the links at the top of  
http://savannah.nongnu.org/download/avr-libc/released/
binutils-2.14 with the info fix patch applied
gcc-core-3.3.1 with the combine and info fix patches applied

I built and installed binutils 2.14 using /usr/local/avr as my prefix  
dir.  I have /usr/local/avr/bin and sbin in my PATH.

When compiling gcc, I get a few errors, and I'm not sure what to do  
about them.  I looked at builtin-attrs.def, but was unable to figure  
out why gcc complains about a missing right curly brace.  Below is the  
output of make, minus a _lot_ of "warning: style of line directive is a  
GCC extension" (not noted) and a handful of very similar errors  
(-cut-).  If the entire output would help to figure out the problem,  
let me know.

Thanks,
John
