Instead of putting back that comment about the bug,
how about fixing the bug? Something like the following.
Or perhaps a fix should be put into stdio.in.h so that
all gnulib programs can assume glibc behavior here,
for fwrite? Though this would mean using an extern
function, something that caused trouble with libvirt...
