There was one of those famous Autoconf debates about it.  Alexandre
will know better than I do.

This is a big problem with *ourselves*: we should put even more
comments.  In fact, you should look in the archives of autoconf@, IIRC
this issue was raised not so long ago, and Pavel (IIRC), suggested
that we'd better generate with -o and with -g -o, and compare the
sizes to decide if we keep -g or not.
