+implementing:

+- userland

+- libc
+  - print_char
+    - requires a 3 parameter syscall to 80h (Linux)

+not implementing:
+- libc
+  - printf

+      - requires
+        - either inline assembly
+        - linker and calling convention
+- preprocessor
+  - have a cat building up the required modules instead
+  - needs file operations (at least open, close, read)
+  - needs a file system on the host and the destination
+    (alternative: have a tape-like file system)
+- linker
+  - have compilation units needs a linker do build
+    an executable
