|
|

134 |
* ALL_STATIC -- (ignored) building various static libs, or building an

135 |

|
|
|
136 |
* Thus,
|

|
137 |

|
138 |
* this bit of #ifdefs will define the 'correct' config variables based on
|
|
|
139 |
* that. If a cygwin user *wants* to define 'PNG_USE_DLL' that's okay, but
|
|
|
140 |
* unnecessary.

150 |
* __declspec(dllexport) / __declspec(dllimport) and friends. Therefore,
|
|
|
151 |
* we don't need to worry about PNG_STATIC or ALL_STATIC when it comes
|
|
|
152 |
* to __declspec() stuff. However, we DO need to worry about
