source: code/branches/mac_osx/src/external/ois/win32/Win32JoyStick.cpp @ 8687

Last change on this file since 8687 was 8070, checked in by rgrieder, 15 years ago
Fixed OIS v1.3 build for MinGW 3.4 and hopefully also for the new versions. This fix needs some additional files in the dependency package though.
Property svn:eol-style set to `native`
