it looks like this is in essence inlining the run-time library routine. In which case, shouldn't you only do it if inlining is enabled? For example, it seems rather odd to do this if compiling with -Os.
Actually, measurements showed that this instance of inlining is a win for both performance and code size, so it’s a good candidate even for -Os. Note that we inline string concatenation routines for the same reason.
