Build errors: redeclaration of <...> may not have default arguments [-fpermissive]

[gim-]

Build fails on Arch Linux with a few syntax errors like this:

error: redeclaration of ‘template<class T> void asl::combineArrays(T*, T*, T*, unsigned int, T*, unsigned int)’ may not have default arguments [-fpermissive]

OS: Arch Linux x86_64
ASL version: 0.1.2

I can confirm this issue on Fedora 22.

We have fixed this without relying on -fpermissive - will release it soon...

Still the same issue persists: http://pastebin.com/Y2d27UPM
CMake version: 3.2.3
Defining the CMAKE_CXX_FLAGS="-fpermissive" in this block works as a workaround again.
