Texture Combine not supported? Why?

Texture Combine not supported? Why?

I have an OpenGL program that isn't rendering properly, the print SPU
tells me that it is calling:
TexEnvi( GL_TEXTURE_ENV, GL_SOURCE0_RGB, GL_TEXTURE )
TexEnvi( GL_TEXTURE_ENV, GL_OPERAND0_RGB, GL_SRC_COLOR )
TexEnvi( GL_TEXTURE_ENV, GL_SOURCE1_RGB, GL_PRIMARY_COLOR )
TexEnvi( GL_TEXTURE_ENV, GL_OPERAND1_RGB, GL_SRC_COLOR )
TexEnvi( GL_TEXTURE_ENV, GL_COMBINE_RGB, GL_MODULATE )
TexEnvi( GL_TEXTURE_ENV, GL_RGB_SCALE, GL_LINES )
TexEnvi( GL_TEXTURE_ENV, GL_SOURCE0_ALPHA, GL_TEXTURE )
TexEnvi( GL_TEXTURE_ENV, GL_OPERAND0_ALPHA, GL_SRC_ALPHA )
TexEnvi( GL_TEXTURE_ENV, GL_SOURCE1_ALPHA, GL_PRIMARY_COLOR  )
TexEnvi( GL_TEXTURE_ENV, GL_OPERAND1_ALPHA, GL_SRC_ALPHA )
TexEnvi( GL_TEXTURE_ENV, GL_COMBINE_ALPHA, GL_MODULATE )
TexEnvi( GL_TEXTURE_ENV, GL_ALPHA_SCALE, GL_LINES )

I noticed that the Chromium documentation says
"Texture Combine test (Test number #85) not supported (not an error)."

I noticed that the above shows that the program is setting the
GL_COMBINE_RGB and GL_COMBINE_ALPHA.

Could the problem with my program be related to the lack of support
for Texture Combine? If yes, why isn't this supported?

Thank you for your time,
