[avr-gcc-list] problem building gcc 4.3.2

[Galen Seitz]

Hi,

I'm trying to build RHEL/CentOS packages that match the latest winavr 
release.  I've downloaded Eric's patches and incorporated them into 
the build process.  The build dies during libgcc with this error:

Configuring in avr/libgcc

See `config.log' for more details.


When I look at avr/libgcc/config.log, I see that xgcc is being passed 
i386 options, which can't be correct:

configure:2588: /home/galens/rpm/BUILD/avr-gcc-4.3.2/build/./gcc/xgcc 
-B/home/ga

cc1: error: unrecognized command line option "-march=i386"
cc1: error: unrecognized command line option "-mtune=generic"
conftest.c:1: warning: unwind tables currently require a frame pointer 
for corre
ctness


I haven't been able to figure out what I've done wrong.  Do Eric's gcc 
patches require a bootstrap?  If so, what is the recommend way of 
doing this?

thanks,
