The "page: 7 of 9" use was the last change I made.
I found that error too, corrected it, but uploaded the old file.
I know I'm stupid, but I hope it helps that I'm very sorry about that
mistake.

I removed the wrong and put the right version under:
http://groups.yahoo.com/group/boost/files/make_string/make_string2.cpp

The correct way was to remove the
  ostream& operator<<(ostream&, const make_basic_string&)
and use
  << (make_string() << 7 << " of " << 9).str()

Referening a signature I use sometimes:

"Sometimes when I'm talking, my words can't keep up with
my thoughts. I wonder why we think faster than we can speak."
  -- "Probably so we can think twice."

"Sometimes when I'm uploading, my thoughts can't keep up with
my mouse-clicks. I wonder why we upload faster than we can think."
