/* If we're on 10.4, fine, we'll just try the default library name. For
* earlier versions of Mac OS X, try the legacy library first.
*
* Having a kludge like this is unfortunate, but necessary for the following reasons:
* 1. We need two libraries to support Mac OS X 10.2, 10.3 and 10.4. We could
* cover 10.2, 10.3 and 10.4 with one gcc 3 compiled library, but then we
* loose intel mac support. Instead, we'll distribute two versions of the lwjgl
* native library, the default and a legacy one.
* 2. The default library will be universal ('fat') with both intel and powerpc support
* compiled in. This requires gcc 4, and makes the library unusable on Mac OS X 10.3
* and earlier (actually 10.3.9 has the required gcc 4 libraries, but we'll ignore that).
* We could still choose to load the default library first, and the legacy one later,
* but a bug in the Mac OS X java implementation forces a java program to exit
* if the loaded library has a missing dependency (The correct behaviour is to throw
* an UnsatisfiedLinkError, like on linux and windows).
* 3. If the LWJGL program is launched with an intelligent ClassLoader, this issue can be avoided
* altogether, and the legacy library naming can be avoided too. For example, when
* using webstart, one can supply two nativelib references, one for Mac OS X 10.4
* (the default library), and one for earlier Mac OS X (the legacy library). This is the
* preferred way to deploy the libraries. The legacy naming is for the users that don't want to
* mess around with libraries and classloaders. They can simply make sure that lwjgl.jar
* is in the classpath and that both the default library and the legacy library is in the native
* library path (java.library.path).
