Current snapshots of GCC 4.3 issue the following warning (with -Wextra,
for example)
basetexture.c:437: warning: comparison of unsigned expression < 0 is always false
basetexture.c:438: warning: comparison of unsigned expression < 0 is always false
Indeed WINED3DTEXF_NONE is 0 and thus the comparison is a noop. I see
three ways to handle this:
1. the straightforward patch below,
2. adding an #ifdef WINED3DTEXF_NONE > 0 around those two conditions,
3. living with the warning.
I'm not particularily fond of any of these three but would like to avoid
the third one because this very compiler warning has already found us a
quite a couple of bugs. I'll be happy to provide a patch for the second
options or any other alternative you can think of.
Thoughts?

ChangeLog:
Remove noop check in IWineD3DBaseTextureImpl_Appl().
