[aur-general] Unresponsive maintainer (=TU)

Hi, On 10 October I discovered an error building mysql-connector-c++ when (Oracle's) MySQL [1] is build with compiler flag -fno-rtti. I posted a comment asking about the removal of this flag in PKGBUILD (it only saves a bit of memory, but everything works fine without this flag). On 29 October I sent the maintainer (cc'ed here) an email politely asking again to remove the problematic flag. Until now I didn't get a response, nor did he change his PKGBUILD. Now someone else is asking the same in a comment. What to do in this situation? Filing an orphanage request seems too harsh to me. Moreover, the maintainer is a TU. Any advice is welcome.
