State-Changed-Why:
    
    I don't fully understand it either.  I think I see what's
    happening, but I don't see how it could.
    
    gin@mo.msk.ru, is this still happening for you?  Lots of
    changes have been made since 3.0.2.
    
    In particular, I don't see how this can happen with the
    default "gmake bootstrap-lean" and no other arguments
    or overrides.  Nobody else has experienced this with the
    default setup.
    
    The problem would seem to occur when trying to override
    a makefile variable on the command line; this gets tricky
    when recursing.  The construct $(foo) is simply a variable
    in makefiles, but in a POSIX Bourne shell it is the same as
    writing `foo` which means something very different.
    
    A cleaner makefile would use ${foo} in all cases, because
    brace-expansion means the same thing (variable expansion)
    in makefiles as it does in shells.
