Patch for rgl with gcc 4.0 in R 2.3.0 on OS X
...ramework/Versions/2.3/Resources/library/rgl'
---------------------
2) The fix is below. It seems that gcc-4.0 does not want to convert an int*
directly to a const GLint*, maybe because it might be possible to
fool around with the underlying variable. To deal with this, I defined a
GLint named viewgl and set it equal to the dereferenced value
of the int* view. I then passed in the address of viewgl to the gluProject
routine. This eliminated the error messages and allowed compilation.
