First, thanx for answers.
I don't change any compiler- or linker-options
and the 'AsteroidsGame' from the 'DustyEngine'
seems to work with the origin-irrlicht-dll.
Other simple programs haven't (unfortunatly)
any bugs and the engine compile without
warnings.
It was an good idea to update the dx-sdk.
(Puuhh, 222Mb without a flat-line)
Now my result library is now 32 kB smaller.
Hurray, but it's not working, too
I'm confused about the DX-SDKs:
When I'm uninstall the SDK before I'm install the
december-"Update", then the compile fails
because of missing DX8 thinks.
What is then the right way to install
"the DirectX 9.0 c"-SDK ??
First 9.0a, then 'dec2004-Update' or ...???
(Give it a "irrlicht-compatible DX-SDK Install-Tutorial??)

It's a pity, what Micro$oft makes with DX-SDKs
- 8a..b..,9a..b..c, 'summer-update',
'december-update', 'MyUncleTomsWife-Update' ...
(and ever >200Mb for an UPDATE) GGggrrrrhhhh
