Oh look, someone on SO is asking for (nearly) the exact thing I wrote before: a glibc-less "Hello world" for the Hurd.
Should I send them the link to https://github.com/bugaevc/hello-hurd? ?
Except they want it to be short and in assembly, not C. Guess I could just dump the asm GCC generates? It would not even be _that_ long in the TINIER config.
