Why would we want to put into our compiler a TARGET-SPECIFIC syntactic
extension to handle the rather generic concept of a fixed-size vector?
would we want to add a configure mechanism to do that?
Let me answer for you: We don't.
What we want is a *generic* machine-independent syntax, with optional
target-specfic optimization patterns. If you don't want to or can't do
no problem. Feel free to maintain your own tree with whatever extensions
you want - it's Free Software. But I will vote against any suggestion to
allow such code to be checkled into the CVS mainline.
