libstdc++-v3 PATCH for bootstrap error related toptrdiff_t

[Mark Mitchell]

  I'm afraid your patch

    2000-11-16  Mark Mitchell  <mark@codesourcery.com>

	  * config/c_io_stdio.h (streamsize): Make it a typedef for
	  ptrdiff_t.
	  (wstreamsize): Likewise.

  breaks bootstrap on i386-unknown-freebsd4.1 with --enable-cstdio=stdio and
  also sparc-sun-solaris2.8 seems to be affected, as ptrdiff_t is defined in
  stdlib.h resp. cstddef (according to ISO C++) which we don't include.

Doh!  Should have thought of that.

  How about the following patch? I have not been able to do a full bootstrap
  due to other problems, but it definitely solves the problem at hand.

That's fine.

Thanks,
