     This error indicates that the bootstrap compiler is picking up the
     specs file for the just-built compiler; naturally this cannot work.  I
     am not sure how it could have happened -- please repeat the command I
     quoted, with an additional -v option tacked on the end, and post the
     output.

 Wow, this is old.  I did track down one way this could happen, and
 papered it over by removing underscore.c.
 See http://gcc.gnu.org/ml/gcc-patches/2002-09/msg00271.html (ignore
 the subsequent thread, which is mostly sound and fury about who owns
 the c++filt executable).
 
 I hesitate to call the problem resolved, however, because there is
 nothing intrinsically *stopping* Make from generating $build/gcc/specs
 before we are done using the bootstrap compiler.  I don't know why the
 bootstrap compiler was reading $build/gcc/specs in the first place,
 but my theory is it was a bug in gcc 2.95, which it is far too late to
 fix now.
 
 A larger question is why do we generate that file at all?  It is an
 exact dump of the specs compiled into the driver; as such I see no
 purpose for it other than to slow down the driver by making it read
 the file on every invocation.  People who want to hand-hack the specs
 file can always use -dumpspecs to get a copy first (of course, this
 would need documentation, if we made that change).
