Hello again.
Today I've compiled opus-tools-0.1.7 with opus-1.1-beta on two other Ubuntu systems without problems.

Ubuntu-11.04(Natty)
$ gcc --version
gcc (Ubuntu/Linaro 4.5.2-8ubuntu4) 4.5.2

Ubuntu-12.04(Precise)
$ gcc --version
gcc (Ubuntu/Linaro 4.6.4-1ubuntu1~12.04) 4.6.4


So maybe there is something weird about the compiler used in the Peppermint Three OS.
$ gcc --version
gcc (Ubuntu/Linaro 4.6.3-1ubuntu5) 4.6.3


I will be happy to test any patches, but (imo) it's not worth investigating further for what is now an obsolete OS.
