[Mesa-users] Missing GL_ARB_texture_float with software rendering

According to some internet searches [1] it looks like the software
renderer supports GL_ARB_texture_float, but when I run
"LIBGL_ALWAYS_SOFTWARE=1 glxinfo|grep texture_float" on my system
nothing comes up. Do I need to compile Mesa with special options? Or
is this a bug I should report? Full output of glxinfo at end of email.
Thanks,
