Aubio patches to fix a number of Linux build issues.

[Mo DeJong]

Hi Paul

Your aubio-0.2.0beta1 just needs this one patch to build on my Linux box.
I also noticed that you are passing -Werror on the command line. This
was generating a strange error:

gcc -DHAVE_CONFIG_H -I. -I../../../aubio-0.2.0beta1/examples -I../src    -I../../../aubio-0.2.0beta1/examples/../src -I../../../aubio-0.2.0beta1/examples/../ext  -O2 -Wall -Werror -Wmissing-prototypes -Wmissing-declarations -Wno-char-subscripts -Wno-unknown-pragmas -c ../../../aubio-0.2.0beta1/examples/utils.c
cc1: warnings being treated as errors
../../../aubio-0.2.0beta1/examples/utils.c: In function `examples_common_init':
../../../aubio-0.2.0beta1/examples/utils.c:219: warning: value computed is not used

I am not really sure what is up with that, but perhaps -Werror is a bit too strict.

thanks much
Mo DeJong
