Why? That should not affect the operation of printf (but if may well
confuse source-code debuggers).

If it is just your package, then the CFLAGS are taken from
R_HOME/etc/Makeconf. You can either edit that, or you can create a
Makefile in your package's src directory which would give you complete
control. (We don't recommend the later for packages which are distributed
as it is tricky to get cross-platform features right.)
