Using include_next bypasses the default header search path and lets
files later in the include path take priority over earlier files.
This makes replacing libc impossible as the default libc headers will
occur after the libstdc++ headers, and so be picked up in place of
headers inserted at the begining of the search path or appended to the
end of the search path.
Using include_next is a hack to work-around broken combinations of

Using include_next bypasses the default header search path and lets
files later in the include path take priority over earlier files.
This makes replacing libc impossible as the default libc headers will
occur after the libstdc++ headers, and so be picked up in place of
headers inserted at the begining of the search path or appended to the
end of the search path.
Using include_next is a hack to work-around broken combinations of
libraries, and is not necessary in a well constructed toolchain.

Subject: [PATCH 1/2] libc: Remove #include <sys/select.h> from sys/types.h
picolibc's sys/select.h is likely to be replaced by the underlying
operating system version (as it is on Zephyr). Don't include it from
sys/types.h as that version may depend on other definitions in
sys/types.h which haven't yet been defined.

Subject: [PATCH 2/2] tinystdio: Fix snprintf(buf, 0, ...) to not smash buffer
snprintf(buf, 0) should not write anything to the destination, not
even a trailing '\0'. The tinystdio implementation had a signed
comparison bug where this case would cause a null to be placed in the
output buffer at the size of the data that would have been written.
Add a test to make sure snprintf respects the 'len' parameter
correctly.
