Bug#548641: snack: FTBFS with eglibc 2.10

[Ilya Barygin]

Package: snack
Version: 2.2.10-dfsg1-8
Severity: normal
Tags: patch
User: ubuntu-de...@lists.ubuntu.com
Usertags: origin-ubuntu karmic ubuntu-patch

In Ubuntu, we've applied the attached patch to achieve the following:

  * jkFormatMP3.c: #include <math.h> before definition of roundf() to
    fix FTBFS (LP: #437336).

We thought you might be interested in doing the same. 

The build fails with the following error:
