While we should probably fix this behavior of "configure" to do the
same thing as an autoconf-generated "configure", I don't think that
this problem makes having a "configure" script any less of a good
idea. The "configure" script handles the common case very well; it's
much easier for people accustomed to *nix software than bjam will
ever be.

Let me put it this way: since I wrote the "configure" script for
Boost, the number of times I've been told that Boost is too hard to
build (e.g., at conferences and workshops) has decreased
*drastically*. bjam is powerful, but it's non-traditional. For all of
the failures of autotools (and there are many!), *nix programmers
understand how to build autotools-based projects and can do it very,
very easily. "./configure && make && make install" is enough for the
vast majority of the open source projects in the world.
