Stepping on reserved names is something that you can often get away
with (if you don't conflict now, how likely is it that libc will
actually introduce a future symbol that will conflict later?), so this
is change is more on the theoretical side.  But I have no objections,
and as you proved, it's a very easy mechanical fix once we even bother
to identify that reserved name clashes could be a potential porting
issue.  I've probably spent more time writing this email than you did
in creating the patch proper (if you exclude the subsequent time
testing that it builds and passes 'make check-valgrind'...)
