Wow, that's encouraging, one google revealed the author of libsndfle
claiming some processors like arm did not have lrintf so I was imagining
an incompatibility.
That is the same floating_point_test by the looks. The other thing I was
thinking was if it was scaled against time it would give a poor result,
but if you have had it passing that's good.
In the autobuilder I have spotted '--disable-external-libs' so I'll try
that before going to the autobuilder libsndfile in a last effort.
It is good to hear that gcc 4.7.4 and vfp is working so well, is the
Pandaboard the only one that can benefit?
