Whole lotta compiler warnings, please advise

[toysnob]

I just built my app for the first time after including the CEGUI.h and d3d9renderer.h

Without actually referencing any of CEGUI's classes, just by including them, I have now gotten a bunch of compiler warnings. Here they are. I'm wondering if they are of any concern or if they can be ignored?

[lindquist]

try to disable "detect 64 bit portability issues"

[gcarlton]

No, its a valid point. I personally turn the warnings level down before including any cegui header file, but it would be better if they were all clean up to level 4.

[CrazyEddie]

_mental_ is doing some work on 64Bit compatability, until I get such a system on which I can test stuff (which is unlikely for at least another 18 - 24 months), I will not be doing anything related to that myself.

I don't like warnings either, I have generally kept them to a minimum, but as for warnings at higher levels in VC++, I may get around to fixing them all at some stage, or I may not.
