Preprocessing oddity breaks binutils

   In the binutils case, what's happening is that a generated lexer (from
   lex) is being placed in the objdir, along with a a generated include
   file full of tokens.  However, there's *already* a file of tokens in
   srcdir.  When compiling the lexer, we get the old file of tokens,
   because the lexer contains #line directives referring back to the old
   lexer.

   Perhaps, in the interests of portability, some kind of modification to
   binutils or automake is a good idea as well.  (This is happenning with
   ldlex.l, ldgram.h, and friends in the `ld' subdirectory of binutils.)

There is something odd going on with your build, because the CVS tree
does not include any generated files.  It does include ldlex.l (not a
generated file) but it does not include ldgram.h (a generated file).
