Infrastructure

We do have the following operating systems in the bugzilla version list picker:

• All
• Linux (All)
• Android
• Windows (All)
• Mac OS X (All)
• iOS
• FreeBSD
• NetBSD
• OpenBSD
• BSD (Others)
• Solaris
• Cygwin
• AIX
• HP-UX
• IRIX
• Interix
• other

I really would remove

• Cygwin
• AIX
• HP-UX
• IRIX
• Interix
• other
  as these are NOT supported. *BSDs and Solaris do have community builds.(and why is OS2 missing in this list:-p)
  Why Cygwin?

https://bugs.documentfoundation.org/buglist.cgi?list_id=568446&op_sys=Cygwin&op_sys=AIX&op_sys=HP-UX&op_sys=IRIX&op_sys=Interix&op_sys=other&order=Importance&query_format=advanced&resolution=---
This link gives only ONE open result of opened mentioned bug reports.

If somebody still wants all these Unix addressed, maybe combine them to a simple category Unix. (but then do the same for *BSDs)
