Why? There is no side effect if it is tested for on platforms other than
cygwin. And by being a little bit more generic less changes will be
needed to work with (say) WINE. Or on a cross-compile chain.
And the developer writing the configure test will still need to decide
what to do if it fails && they are compiling on cygwin, so they still
need a case statement.
