I guess that this would not work: #include <stdio.h> #include "unlocked-io.h" would not make the unlocked IO routines visible, because <stdio.h> gets skipped when it gets included a second time. Right?
If we treat __UNIX_PUTC like we treat _GNU_SOURCE then we should be OK, since __UNIX_PUTC will be defined in config.h and thus the first <stdio.h> will see it.
