I think a patch adding descriptions to the docs would be an improvement.
Would you like to submit one?
Thanks,

I could, but the only thing I would do would be something like:
The meaning of these flags can be inferred from the comments in
gcc/config.in.

I tried downloading and editying
http://gcc.gnu.org/install/configure.html; however, I soon ran into
problems. Attached is a diff between the original .html and the
modifications I tried. It shows that even the comments in config.in
are confusing :(
