I have installed Cygwin 1.1.0 (from cygwin/latest) under Windows 2K.

*  how to install snapshots ? 
   ~~~~~~~~~~~~~~~~~~~~~~~~

   The setup.exe contained in cygwin-inst-20000511.tar does nothing 
   when I run it.
   I tried to dispatch the files myself, but then my compils go wrong.
   Where to put the (310k) lib/libiberty.a ? 
   Where go i686-cygwin/* ? 
   To / or to /usr or to /usr/local ?

*  I'm still trying to compile a CrossGCC i686-pc-cygwin32 -> m68k
   ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

   I choosed target=m68k-coff; what is m68k-aout ?

   I could configure/build/install binutils-19990818 (there are many
   warnings at compile-time).

   BUT I CANNOT BUILD THE gcc-2.95.2-1-src (from cygwin/latest)
                  nor the gcc-2.95.2       (from gnu/gcc).

   my commands:

      cd build-gcc
      ../gcc-2.95.2/configure --target=m68k-coff          \
                              --with-gnu-as               \
                              --with-gnu-ld               \
                              --enable-languages="c c++"  \
                              --with-headers=?????
      make all
   
   I don't have any dir called sys-include. So I tried to put there
   several dirs from ../glibc-2.1.3 (those whose path contain 'm68k')
   but I always get these:

      - warning in libiberty/pexecute.c:379

      - warning in gcc/fixinc/fixincl.c:349: 'SIGIOT' undeclared in
        function 'initialize'

        make[2]: *** [fixincl.o] Error 1

      - warning in gcc/libgcc2.c:41: stdlib.h: not found
                   gcc/libgcc2.c:42: unistd.h: not found

        make[3]: *** [libgcc2.o] Error 1
   
      - ...
        make: *** [all-gcc] Error 2

   I tried to comment out these #include <stdlib.h> and <unistd.h>
   in file gcc/libgcc2.c and in gcc/frame.c, but then I get this:

      - warning in gcc/libgcc1-test.c:101: conflicting types for
        built-in function 'memcpy'

      - gcc/cpp.texi: Error 0

        make[1]: *** [cpp.info] Error 2

        make: *** [all-gcc] Error 2




   I don't know what to do. May be look for newlib ?
   What options, or what patch to apply ?
   
   I really need this cross-compiler for my project at school. 
   Anyone could help ?

   Thank you very much.

Germain Ivanoff
