SELECT_SECTION is defined in sco5.h.   Was this random comment triggered
based on knowing that it needed to be there, or upon seeing that it was
there and somehow suboptimal?


Though I haven't rebuilt with Kean's patch, I have done a full bootstrap
and test with the ASM_OUTPUT_ALIGNED_BSS patch installed and noticed no
difference in the dejagnu output.
