I did consider this.

Sorry, but I must question the point of worrying about an ancient bug
in Solaris. When you have to worry about a standard library function
blithely writing past the end of a buffer, when its C89 era interface
must be passed the size of said buffer, where does it end?

This is not a portability concern, like checking for an INT_MAX return
value from strxfrm() on Windows. The Solaris issue is patently a bug
that existed in some particular release of the Solaris C stdlib many
years ago. The documented behavior of strxfrm() in that library was
surely not "We ignore the bufsize argument".
