How can I turn this optimization off?
Use -fno-builtin-printf.
I'm curious, it's obviously a correct optimization, so why
would you want to turn if off?
You can also use -ffreestanding to disable it (and other
similar ones). If you are working in an environment which
only has printf, the conversion to puts is not helpful.
I would have thought that configure would automatically know
there was no puts, and not do the optimization if no puts
is available???
