mycroft 913449a520 Disable the atexit(_IO_cleanup) for two good reasons:
1) There is already a destructor that does this.  The atexit() is superfluous.
2) If libstdc++ is loaded dynamically by dlopen() and then is removed by
   dlclose(), the pointer is no longer valid and the program would core dump
   at exit() time.  (This caused xmms to core dump at exit when xmms-sid was
   installed, for example.)
NOTE: THIS NEEDS TO BE APPLIED TO THE `TOOLCHAIN' VERSION.

HOW TO BUILD A CROSS COMPILER
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
[Section to be written.]

See also: http://www.netbsd.org/Documentation/cross/


IMPORTED VERSIONS
~~~~~~~~~~~~~~~~~
The following software is in gnusrc/gnu/dist/toolchain, in a unified build
structure:

    gcc-2.95.3
    binutils-2.11.2
    gdb-5.0


IMPORT STEPS
~~~~~~~~~~~~
1. All distributions were unpacked and all `.cvsignore' files were
   removed.

2. All files in gcc's `include' top level directory were removed from
   binutils's `include' top level directory (these are the libiberty
   include files).

   cd gcc-*/include; for f in *; do rm -f ../../binutils-*/include/$f; done

3. The gcc distribution was imported in one shot into
   gnusrc/gnu/dist/toolchain, including the recursive build structure.

4. The binutils distribution was stripped down to the following directories,
   with no files at the top level:

   bfd, binutils, gas, gprof, include, intl, ld, opcodes

5. Binutils was imported into gnusrc/gnu/dist/toolchain, which included
   only the subdirectories above.

6. The gdb distribution was stripped down to the following directories,
   with no files at the top level:

   gdb, mmalloc, readline, sim

7. Gdb was imported into gnusrc/gnu/dist/toolchain, which included only
   the subdirectories above.
