Sorry about the delay in responding but I've been busy with a son
with 2 broken arms, and a lot of other things.

Last night I downloaded both latest CVS trees. Binutils from the RedHat CVS
and gcc from the GCC CVS. Binutils compiled without any problem. I now get
some different errors on the compiler. I did compile a C program as you
requested. I didn't get any error.

Here is the result of the compile of gcc. I did assemble the generated file
with avr-as generated by the binutils and got no error. gcc seems to be
the thing that is broken right now.

I have binutils installed on /usr/local/bin


Adding -save-temps in /usr/src/packages/BUILD/avr-gcc-010317/gcc/libgcc.mk
to the first compile I get this
