173  * (no define) -- building static library, or building an
174  * application and linking to the static lib
175  * 'Cygwin' defines/defaults:
176  * PNG_BUILD_DLL -- (ignored) building the dll
177  * (no define) -- (ignored) building an application, linking to the dll
178  * PNG_STATIC -- (ignored) building the static lib, or building an
179  * application that links to the static lib.
180  * ALL_STATIC -- (ignored) building various static libs, or building an
181  * application that links to the static libs.
182  * Thus,
183  * a cygwin user should define either PNG_BUILD_DLL or PNG_STATIC, and
184  * this bit of #ifdefs will define the 'correct' config variables based on
185  * that. If a cygwin user *wants* to define 'PNG_USE_DLL' that's okay, but

191  * PNG_STATIC

196  * __declspec(dllexport) / __declspec(dllimport) and friends. Therefore,
197  * we don't need to worry about PNG_STATIC or ALL_STATIC when it comes
198  * to __declspec() stuff. However, we DO need to worry about
199  * PNG_BUILD_DLL and PNG_STATIC because those change some defaults
