The requirement for Cygwin is a non-issue as I see it.
Several groups have already done Win32 ports that do not require Cygwin.
The company I work for is one example.
The group in Japan:

is another.
I saw some others besides these.
In other words, you don't have to have Cygwin to run PostgreSQL under
Win32 environments.
