2001-02-07  Benjamin Kosnik  <bkoz@redhat.com>

        Clean up stdexcept.
        * include/bits/stringfwd.h: New file.
        * include/bits/stl_string_fwd.h: Remove.
        * include/bits/localefwd.h: Remove declaration for allocator.
        * include/bits/std_iosfwd: Same.
        * include/bits/std_string.h: Include it.
        * include/bits/std_ios.h: Remove include.
        * include/bits/basic_string.h: Tweak.
        * libsupc++/new: Format.
        * src/Makefile.am (base_headers): Add stringfwd.h, remove
        stl_string_fwd.h
        * src/Makefile.in: Regenerate.
        * include/bits/std_stdexcept.h: Rewrite.
        * src/stdexcept.cc: Same.

seems to cause a build failure on an i686-pc-linux-gnu.

A 'make bootstrap' fails with:

Any idea?
