Title: dev-cpp/eigen: fix build issue and some warnings with gcc-4.7

I've backported 2 patches from upstream to fix a build issue and to remove one warning.
All details can be found in the patch file.

On a side node, I'm quite new to PR on github, so this may not be able to merge easily.
Sorry for any inconvenience
