Re: Suggestion: Use -pipe by default

["Tim Prince" <tprince at computer dot org>]

I used to use Irix 6, where -pipe isn't supported.  If someone wanted to
find a way to configure -pipe by default for those systems where it works,
we might try it.  If it's known to work on all gas systems (at least for
piping compiler to gas), it might be on by default for those, since the
configure checks for gas already.  There are a number of cases to check.
