Hi Juegen,
shure, the different libraries will be generated even either multilib is
enabled or not (valid for 1.6.2). Since 1.7.x the option --enable-multilib
will fail the configuration stage :-(
./configure --host=avr --enable-multilib
configure: WARNING: unrecognized options: --enable-multilib
There is no configuration option for avr-libc -- have a look to the AVR-Libc
users manual:
http://www.nongnu.org/avr-libc/user-manual/install_tools.html
I think we have to leave multilib enabled for binutils and gcc. AVR-Libc needs
a multilib enabled infrastructure of binutils and gcc -- not himself.
br,
Stephan
