I've pushed the v4 patch. Thanks

Checking symbol versions in libc on Solaris confirms that iswblank was
added much later than others such as iswspace – only a well patched
Solaris 10 will have it while the others are in Solaris 9 and perhaps
earlier. Whether anyone still builds zsh on a system that lacks it is
harder to tell.
