Thanks for letting me know.

I found some info regarding this error here:
http://stackoverflow.com/questions/8188849/avr-linker-error-relocation-truncated-to-fit

after which I tried adding -mno-short-calls to the failing xgcc call.
This did not change a thing however.

I'm wondering if it's at all possible to compile libstdc++ for avr32.
Following project seems to suggest it is:
https://github.com/jsnyder/avr32-toolchain/blob/master/Makefile
I looked through some of the options, but did not notice anything out
of the ordinary. One thing I did see is that for the avr32-toolchain
project, -Os is used. Could this fix the relocation truncation?

Any input is welcome...

Best regards,
Thomas
