Most of the discussion has moved to jack-devel. It was too technical and
OT for LAU.

You still use -O1 -- That won't work with gcc-4.7.0 and jack2 due to a
gcc-bug [most likely] (see jack-devel -
http://permalink.gmane.org/gmane.comp.audio.jackit/26057 ) -- use -O0 as
David suggested or better: gcc-4.6 that may also work-around the libm
issue, as well.
As for libm: Maybe one of the following can shed some light.
ls -l /usr/lib/gcc/i686-pc-linux-gnu/4.7.0/../../../libm.so
ls -l /usr/lib/libm.so
file /usr/lib/libm.so
It's also mentioned twice: '-lm', '-lstdc++', '-lm' but that
should not
make a difference.
