81
* PNG_BUILD_DLL -- building dll
82
* PNG_USE_DLL -- building an application, linking to dll
83
* (no define) -- building static library, or building an
84
* application and linking to the static lib
85
* 'Cygwin' defines/defaults:
86
* PNG_BUILD_DLL -- (ignored) building the dll
87
* (no define) -- (ignored) building an application, linking to the dll
88
* PNG_STATIC -- (ignored) building the static lib, or building an
89
* application that links to the static lib.
90
* ALL_STATIC -- (ignored) building various static libs, or building an
91
* application that links to the static libs.
93
* a cygwin user should define either PNG_BUILD_DLL or PNG_STATIC, and
94
* this bit of #ifdefs will define the 'correct' config variables based on
95
* that. If a cygwin user *wants* to define 'PNG_USE_DLL' that's okay, but
98
* Also, the precedence order is:
99
* ALL_STATIC (since we can't #undef something outside our namespace)
102
* (nothing) == PNG_USE_DLL
104
* CYGWIN (2002-01-20): The preceding is now obsolete. With the advent
105
* of auto-import in binutils, we no longer need to worry about
106
* __declspec(dllexport) / __declspec(dllimport) and friends. Therefore,
107
* we don't need to worry about PNG_STATIC or ALL_STATIC when it comes
108
* to __declspec() stuff. However, we DO need to worry about
109
* PNG_BUILD_DLL and PNG_STATIC because those change some defaults
110
* such as CONSOLE_IO and whether GLOBAL_ARRAYS are allowed.
