Which is extremely misleading IMHO.  Linux is an operating system;
Cygwin is not.  Cygwin is a POSIX/UNIX API layer for Windows.  And, IIRC,
the POSIX and Single UNIX specifications trump Linux behavior when defining
Cygwin semantics.

No, now we continually have to explain why you can't install said
x86 Linux binary/package and run it under our Linux emulator.  Heck, you
can't even *compile* said Linux firewall/router/proxy server etc. under
our Linux emulator.  Doesn't sound like much of an emulation to me.

Since when do you needed to recompile something to use it on an
emulator?  Recompiling a program to use a different API is understandable.

I would love to understand this decision too.
