It is, and as the attached session transcript shows, it WJFFM.

Dunno.  An incomplete installation manifest, perhaps?  Did you install
with an early version of mingw-get, which which may not have recorded
the files list?

The above would be covered by:

  $ mingw-get show -files package-name-bin
  $ mingw-get show -what-provides foo.exe

(or some such), which are already in my ideas pool for some future
release; (of course, neither works at present).  Maybe we should collect
these ideas into a TODO file within the distribution, or
on a feature request ticket.
