Some people who want to build GHC under Mac OS X platform find that
 HOpenAL's configure.ac can't find OpenAL framework. And If they compare
 with some package's configure.ac, they find OpenAL package's configure.ac
 is different from OpenGL, GLUT and ALUT packages'.

 shelarcy already made patch for its problem. How about apply this patch to
 fix HOpenGL's configure.ac bug?

 This patch fix Windows bug, too. Because cufigure.ac uses CALLCONV=stdcall
 on *-mingw32 case, although it has comment like this: "NOTE: For some
 obscure/unknown reason, OpenAL uses ccall, even on WinDoze...".
