clang-10 fails to compile 1.10.2: error: no member named 'fabsf' in the global namespace; did you mean 'fabs'?

I think this is because you use the C++ compiler to compile the C file x11.c. This isn't allowed and the compiler gets confused.

Thanks to remember. I know this is an ugly part and I didn't care about as long as it ran well (all in one makefile $(CXX) line). Thus, I've now some work with the makefile.

C code is now separated from C++ code in dfdece8e1b0e485decc9cc6c07138d19b208f61f . I had a bigger fight with the linker . GCC/G++ should work correctly. @yurivict please let me know if it works with Clang too. (override will be fixed later)

It builds now, thanks.

There are a lot of build warnings though:
