Hi,

fso is quit untested with none GNU libcs and we partly depend on it. I
wrote a short patch which add a --enable-no-gnuism switch for configure,
but want to talk to Michael, before commiting it. Could you test it and
report more gnuism in our code? And is possible to get a backtrace with
uClibc which is not gnuism, but available in all none-GNU
implementations?

Regards Frederik
