Automatically running autoreconf?

[Bryan O'Sullivan]

The fact that most packages don't have autoconf encumbrances means that 
I almost inevitably forget to run autoreconf before building a package, 
which regularly leads to heartburn on my part.

It seems to me that it would be useful if "build" ran autoreconf if 
necessary.  If this seems sane, I would be happy to cook up a patch. 
What do people think?
