Yes, I get a compile error on Nvidia otherwise:

fixme:d3d_shader:print_glsl_info_log Info log received from GLSL
shader #21:
fixme:d3d_shader:print_glsl_info_log     Fragment info
fixme:d3d_shader:print_glsl_info_log     -------------
fixme:d3d_shader:print_glsl_info_log     0(5) : error C7532: global
type sampler2DRect requires "#version 140" or later
fixme:d3d_shader:print_glsl_info_log     0(5) : error C0000: ... or
#extension GL_ARB_texture_rectangle : enable
fixme:d3d_shader:print_glsl_info_log     0(10) : error C7531: global
function texture2DRect requires "#extension GL_ARB_texture_rectangle :
enable" before use

This is on Nvidia 319.12, with ARB_texture_non_power_of_two disabled
to test the RECT codepath. The d3d9 visual test uncovers this problem.
