Have you tried recompiling all libc with this?

It fails for me:
gcc ... -c doprnt.c
cc1.exe: warnings being treated as errors
In file included from ../../../../include/libc/file.h:9,
                 from doprnt.c:15:

../../../../include/libc/ttyprvt.h:84: warning: declaration of `y1' shadows global declaration

And shouldn't the parameter names be prepended by "_" anyway?


Right,
