/* Special munging to support doing things the 'cygwin' way:

 *   PNG_BUILD_DLL -- building dll
 *   PNG_USE_DLL   -- building an application, linking to dll
 *   (no define)   -- building static library, or building an
 *                    application and linking to the static lib
 * 'Cygwin' defines/defaults:
 *   PNG_BUILD_DLL -- (ignored) building the dll
 *   (no define)   -- (ignored) building an application, linking to the dll
 *   PNG_STATIC    -- (ignored) building the static lib, or building an
 *                    application that links to the static lib.
 *   ALL_STATIC    -- (ignored) building various static libs, or building an
 *                    application that links to the static libs.
 * Thus,
 * a cygwin user should define either PNG_BUILD_DLL or PNG_STATIC, and
 * this bit of #ifdefs will define the 'correct' config variables based on
 * that. If a cygwin user *wants* to define 'PNG_USE_DLL' that's okay, but
 * unnecessary.
 *
 * Also, the precedence order is:
 *   ALL_STATIC (since we can't #undef something outside our namespace)
 *   PNG_BUILD_DLL
 *   PNG_STATIC
 *   (nothing) == PNG_USE_DLL
 *
 * CYGWIN (2002-01-20): The preceding is now obsolete. With the advent
 *   of auto-import in binutils, we no longer need to worry about
 *   __declspec(dllexport) / __declspec(dllimport) and friends.  Therefore,
 *   we don't need to worry about PNG_STATIC or ALL_STATIC when it comes
 *   to __declspec() stuff.  However, we DO need to worry about
 *   PNG_BUILD_DLL and PNG_STATIC because those change some defaults
