I've done another clean-up of cygwin-pkg-maint, removing those source packages names which no longer exist after x86 was archived (i.e only existed as x86 packages)
cygwin64-* ORPHANED (Yaakov Selkowitz) 32-bit only by design db4.8 OBSOLETE (Dr. Volker Zell) Obsoletion by db 5.x was done in an unusual way gnome-characters ORPHANED (Yaakov Selkowitz) Presumably build problems on x64. Whole GNOME stack needs looking at hdparm ORPHANED (Christian Franke) Presumably build problems on x64. Cygwin-specific port of hdparm sushi ORPHANED (Yaakov Selkowitz) Presumably build problems on x64. GNOME file manager previewer. Whole GNOME stack needs looking at xemacs ORPHANED (Dr. Volker Zell) Is it dead yet? xemacs-mule-sumo ORPHANED (Dr. Volker Zell) ditto xemacs-sumo ORPHANED (Dr. Volker Zell) ditto xview Jon Turney 32-bit only by design
Note that a lot of long obsolete install package names have also disappeared (e.g. ash, which was obsoleted by dash in 2009, etc.)
