Added to possibility to compile unit tests at maximum warning level.
...
Silenced (amongst others) many conversion related warnings.

Some of our unit tests require mathematical constants and thus we rely on non-ansi code.
...
It seems as if the new standard removed pow(T,int).
M_PIL is only defined when _GNU_SOURCE is defined.

MatrixBase:
...
* support resize() to same size (nop). The case of FFT was another case where that make one's life far easier.
hope that's ok with you Gael. but indeed, i don't use it in the ReturnByValue stuff.
FFT:
* Support MatrixBase (well, in the case with direct memory access such as Map)
* adapt unit test
