Hi,

off topic, but on amd64, it seems kino compiles fine with gcc-4.0 but
crashes on 'open file', whereas it runs when compiled fine with gcc-3.4.
see #319031.

otherwise, fftw3 also fails on m68k, using -O3:

last time i tried building with CFLAGS='-O2 ..' and it also failed, but
oddly:
http://buildd.debian.org/fetch.php?&pkg=fftw3&ver=3.0.1-12&arch=m68k&stamp=1123395597&file=log&as=raw

i guess i should try -O next time then. 

Could someone check that adding the following to debian/rules in fftw3
3.0.1-13 actually works:

<   SETFLAGS := CFLAGS=
