-About
-=====
-
-Terifies if newlib/newlib-nano is correctly included by the build system
-
-At compile time, it checks that:
-
-* newlib-nano header is used when 'newlib-nano' module is included
-  * It defines `_NANO_FORMATTED_IO` macro
-    https://sourceware.org/git/gitweb.cgi?p=newlib-cygwin.git;a=blob;f=newlib/newlib.hin;h=eadafc8a6a51ef7674c004a14777f6a4619115ee;hb=d34336767e45ee801ebb107e40abe4b1acbd3d14#l83
-* newlib or newlib-nano is properly linked
-  * `iprintf` is the same as `printf` or not as mentioned in:
-    https://github.com/32bitmicro/newlib-nano-1.0/blob/f157c994b9a2c4bd8d0cfe9fe8fdd9cd54f8c63b/newlib/README.nano#L32
-
-At runtime, it checks that:
-
-* the same `iprintf` and `printf` test as at compile time
-
-
-Without newlib, the test does nothing.
