This is a warning (which we should look into and probably show up
everywhere). The log contains only one error:
oops :-O
[platform:Error] ../module_cache/module_15.c:558:14: error:

Responsible for that is rpython/rlib/rfile.py, whose create_stdio()
function is called on pypy3 but not on pypy2. Maybe we can add some
hack to avoid entirely the "extern" above, which is not needed anyway
because we #include stdio.h.
Thanks for pointing me in the right direction! Although i don't know how
it works at all, I've created a small patch to suppress the
std(in|err|out) declaration and got pypy3 to compile :-)
Should I put the patches required to make pypy musl compatible at some
issue tracker or will ${someone} consider to take them from the mailing
list?
Warm regards,
Thomas
