Hi all

I have just uploaded MPACK 0.8.0RC2
http://sourceforge.net/projects/mplapack/files/mpack/mpack%200.8.0/mpack-0.8.0-RC2.tar.gz/download
https://sourceforge.net/projects/mplapack/files/mpack/mpack%200.8.0/mpack-0.8.0-RC2.tar.gz/download
.
MD5 (mpack-0.8.0-RC2.tar.gz) = c2aa0cf512a5dfcf2881c69f70953c02

Build fixes.

Build and make check have passed on
* Intel Composer 13.0.1 on Linux.
* Gcc on Linux (Ubuntu, RedHat)
* gcc47 on FreeBSD
