Fails to build (Arch Linux) (Fix in post)

[Markon101]

It fails to build with the following errors. Anyone have any idea what is wrong?

I am building with gcc 11.1.0-1
Edit: This happens with GCC 10 too.
Might this be related to #106?

Edit2: This also doesn't fix it make CC=gcc-9.4.0-1 CPP=g++-9.4.0-1 CXX=g++-9.4.0-1 LD=g++-9.4.0-1

Edit3: Adding #include <cstddef> to the Algorithms.h file worked! That is the fix for this!

[Markon101]

I reopened this issue because it is still an active issue that needs patching.

#120 has been ready for merge for a long time
