MarsSeed [1] filed a deletion request for mingw-w64-nfft [2]: Please delete. Package is 5 years outdated and unmaintained. Not needed by anything in AUR. (Even if up-to-date, this would only be useful for cross-building some software libraries for Microsoft Windows x86_64. For which it is best to set up the complete toolchain locally, rather than use unmaintained PKGBUILDs from AUR.)
