MarsSeed [1] filed a deletion request for mingw-w64-unixodbc [2]: Broken, long-abandoned, outdated. But no mingw-w64 package needs this. I recommend deletion: not useful for any purpose anymore. [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/mingw-w64-unixodbc/
