[sldev] Build errors(in XCode 2.5) with indra.y.h

[Michael Miller]

I found some possible useful information for a patch(at
http://developer.apple.com/releasenotes/DeveloperTools/Xcode/RN-Xcode/index.html#//apple_ref/doc/uid/TP40001051-DontLinkElementID_2).

I do _NOT_ know if this problem affects 10.4 with XCode 2.5. If it
does, we can just do #if XCODE_VERSION_ACTUAL == 0300. If not, we can
do #ifdef MAC_OS_X_VERSION_MAJOR 1050.

Let me know if this problem affects dev tools 2.5 on 10.4, so we can
solve this problem.

Thanks,
Mike
