No. It's Fedora Core 7 on x86_64 ... if that matters ;)

OK. I downloaded the latest binutils configured for a
local directory and built using make CFLAGS=-fPIC.

I then configured simulavrxx using --with-bfd and
--with-libiberty .

I am now able to build simulavrxx.so , but most
of the example directories fail to compile. This looks
like it may be my old avr-gcc.

It seems that there are some missing headers required
by the examples.

For example:
