Hi guys.
I have a curiosity, regarding [1] - I had encountered some
"undefined reference" errors when trying to link the druntime
(compiled for an embedded architecture) without some
implementation of the POSIX thread calls (and other stuff too).
My curiosity is what would change if I removed from the
druntime everything that has to do with mutexes or threads.
Would it be possible for the druntime to run and work properly
on a microcontroller - where those concepts are not necessary?
Could I just remove everything about synchronisation from the
druntime, and classes or Garbage Collector to still work
properly?

Yes, you can stub the thread and mutex interfaces. You will of
course not be able use that or any part of the library that uses
threads but you will be able to get to the main entry point and
run a single threaded D program.
This is something we would want with the druntime API change, a
stub that people can use when they don't need the functionality
or as a starting point for implementing your own version.
