Cygwin still runs on 32 bit and Windows versions down to Vista.

However, since you're asking for a recommendation, some points:

- The limited virtual address space of 32 bit processes is getting
  a big problem for a long time now.  The more packages and the more
  DLLs the distro delivers, the less manageable the situation gets
  on 32 bit machines.  This includes WOW64 on 64 bit.

- time_t on 32 bit is 32 bit.  The effort to change that is not
  managable, and it's not worth it, given that usage of 32 bit
  systems (including WOW64) is at less than 5%, and dropping.

- Newer Cygwin features are partially unavailable (usually faked) on
  older Window versions due to missing API calls.

- Cygwin running on Vista is not going away any time soon.  The extra
  code required to support Vista (and W7, fwiw) is just a drop in the
  bucket, and ripping it out doesn't simplify the code noticably, as for
  XP.

- The same can't be said for 32 bit.  There's a lot of code involved,
  partially assembler code.  Getting rid of that code is really
  an option at one point, what with Windows dropping 32 bit support...

- Older Windows versions are increasingly getting insecure with
  Microsoft stopping updates.

- Windows 10 is not exactly privacy-minded...

Cygwin64 is the recommended release, there are no recommended platforms,
although there are minimum requirements for the code to run, and to build the
code: if you can run it under ReactOS on an old Pentium, good on you! ;^>

That has been determined in the past by the need in a new Wdindows release,
version, or edition, to use a new API, that may not be avoided or skipped for
the oldest versions in a backward-compatible way, as happened when support for
new versions had to be added, so XP support had to be dropped.

The question is nuanced around "what is the recommended platform". Now as
individuals we can recommend anything we want if it works for us.. but we
also aren't expecting to answer all of Fergus's questions when he tries to
get Cygwin working on his system. I think in the end, for the project, the
recommendation would be whatever Corinna recommends as she is the primary
author of the code these days and the one who would be fixing problems
found.

I test my programs and compiled packages on Windows 10, 8.1 and 7. I
think Vista is still supported by Cygwin too, but last I tried it didn't
work and I can't remember why.

No, I run Cygwin64 on Win 7. There is an outstanding W7 update, it appeared a
few weeks ago, but I'm not taking it.
