[avr-gcc-list] Problems building gcc4.0.2 on Linux x86_64

[Marcus Lindemann]

Hi,
I'm having problems with building 4.0.2 on Linux. The Build chokes with

checking for csin in -lm... configure: error: Link tests are not allowed 
after GCC_NO_EXECUTABLES.
make: *** [configure-target-libgfortran] Error 1

This is my configure line
../configure --target=avr --prefix=/opt/avr/Linux --program-prefix=avr- 
--disable-nls --enable-language=c --with-ld=/opt/avr/Linux/bin/avr-ld 
--with-as=/opt/avr/Linux/bin/avr-as

I've googled, but did not find an answer yet. There is some talk about a 
misplace symlink, but in multilib stage, while I fail in fortran 
building stage. I'm wondering why I build fortran, even when I specify C 
as the only language. Can somebody shed some light here?

Thanks
Marcus
