Is cygwin an operating system (according to perlport)?

And how can I know what kind of perl I'm running under?

strawberryperl?
activeperl?
cygwinperl?

According to $^O, yes, it is.

Vanilla/Strawberry Perl are no different from a perl built by hand using
MinGW. That's sort-of the point, actually... You can check for
$Config::Config{cc} eq 'gcc' if you need to know this, but be aware
ActivePerl fakes its %Config if you have gcc installed.

ActivePerl defines the builtin Win32::BuildNumber, so you can test for
ActivePerl with defined &Win32::BuildNumber.

$^O eq 'cygwin'
