Ah, this is a false positive, and actually harmless. One could patch the code 
to not warn about this situation. See the comments in the code about why this 
happens.

d3d9 doesn't support more than 4 vertex samplers, so even if the card supports 
more(a gf8 class card supports 32, due to the uniformed shader architecture), 
we're still fine with 8 fixed function textures and 4 vertex samplers. So you 
can suppress the warning by capping the supported fragment samplers at 4 in 
this check(e.g. max(4, gl_info->fragment samplers)).
