It is not specific to declared textures as it fails on the following as 
well:

sphere{
     < 0, 0, 0 > 2
     texture{
         pigment{ gradient x }
         scale <0.075/pi,1,10>
         warp { cylindrical }
         rotate x*-90
     }
}


 From my experience, it works when it is inside a pigment, finish or 
normal block, but not at the "texture" level.

For example, Jeff's code will work, if modified this way:

#declare P_Flat  = pigment { gradient x }

#declare T_Cylindrical = texture {
     pigment{
         P_Flat
         warp { cylindrical }
     }
     scale <0.075/pi,1,10>
     rotate x*-90
}
