Hi Alexey,

I don't understand why you are seeing svfwprintf.c compiled in your case no
matter what the nano setting is.  The file
is listed under the else section of the check: if NEWLIB_NANO_FORMATTED_IO
so when
this flag is set to true, it shouldn't be included.  I did an
aarch64-none-elf build configured with --enable-nano-formatted-io
and there is no svfwprintf object file in the libc/stdio directory nor in
the final libc.a.

Is there any chance there is something broken with your build or link?
