Hi Denis, thank you for your answer.

Thank you for sharing this with me, I will take a look at what 
you have done there.

Hmm, I will try this as soon as I manage to compile the runtime 
for the Cortex-M, because right now that the big issue for me. 
The 'ldc-build-runtime' tool fails for Cortex-M and I cannot find 
another way to build it. I have also tried to manually compile 
everything, but I could not get anywhere.

I have posted a question regarding the error I get when I try to 
compile the runtime on the Learn thread: 
https://forum.dlang.org/thread/btiahosjluxddsjjnleq@forum.dlang.org.

I would appreciate if you could help me find a way to solve this.

Thank you, I will try to do that too.
