We'll investigate this difference between Newlib and Redlib.
Note that issue 1) is actually not an error. Newlib provides some format checking of the parameters to printf, and these are generating a warning if you use the %u format string instead of %lu. It should be possible to disable this checking using the -Wno-format option.
