Speex dev - Apr 2014 - [PATCH 3/3] Fix file permission of libspeexdsp/scal.c

Hello,

some misc. cleanup patches for speexdsp, nothing big

I'm not sure about how to submit patches, so this is a test balloon :)

ultimately, I'd like to fix the FIXED_POINT issue, see
http://lists.xiph.org/pipermail/speex-dev/2013-December/008465.html

currently, I think the only way to find out how speexdsp has been compiled is
to resample some bytes and observe the output; which is awkard

I plan to post some patches in this direction shortly...

thanks, regards, p.

Peter Meerwald (3):
  Resampler buffer_size is always 160, drop FIXED_POINT #ifdef
  Use fabsf() instead of fabs() since we have floats, not double
  Fix file permission of libspeexdsp/scal.c

Seems fine, fabsf is supported everywhere fabs is?
