You're right. However there does seem to be a difference. In an attempt to track down the failure in Wine I'm trying a simple test case (attached). As a 64 bit application in throws up some compile time complaints but runs, as a 32 bit application is won't link as it fails to find glCheckFramebufferStatus. This is the API call that seems to be causing the problem in the thing I'm trying to run under Wine [1].
