I tend to agree.  And if you do wipe, I suggest installing 10.5, not 10.4.

For interest: in the 10.4 and older SDKs, GLint was typedefed to long. 
In the 10.5 SDK, they changed it to int.  In the 32bit Mac OS X ABI, int
and long are the same size, so in a way they changed nothing.  On the 64
bit ABI, int is 32 bit, and long is 64 bit.  So I guess they made the
change because they wanted GLint to always be 32 bit.  Alas, with C++
name mangling the change between int and long is not as equivalent as it
is in C/Obj-C.
