BIG problems trying to build newlib-1.10.0 on cygwin

["Stephen Biggs" <s dot biggs at softier dot com>]

I'd appreciate any help.  I've been beating my head against the wall with this for a few days now.

I am trying to get gcc-2.95.3 to compile on the latest cygwin for the m68k-elf target.  This is not 
working at all.

I am able to compile and install the first pass of the compiler, just gcc.
Here is the command line that I run  (Note that all of the m68k-elf-* directories are empty at the 
invocation of this command.  binutils and gcc sources have all the applicable patches applied to 
them):

cd m68k-elf-binutils/ && ../binutils-2.10/configure --with-included-gettext --disable-nls --target=m68k-elf && gmake all install && cd ../m68k-elf-gcc && ../gcc-2.95.3/configure --disable-nls --disable-fast-fixincludes --with-included-gettext --without-headers --with-newlib --enable-languages=c --
target=m68k-elf && gmake all-gcc install-gcc && cd ../m68k-elf-newlib && ../newlib-1.10.0/configure --with-newlib --with-included-gettext --disable-nls --target=m68k-elf && gmake all install

I then want to run the command:
../gcc-2.95.3/configure --enable-languages=c,c++ --target=m68k-elf  --with-included-gettext --with-newlib --disable-nls --disable-fast-fixincludes --enable-multilib
LIBS=-lc gmake

I have never been able to get the final build of the compiler to work. It fails when I try to do 
the second full build pass. I did these commands without the "with-newlib", first.

It fails on the first pass as well if I use "enable-languages=c,c++"... seems to be something wrong 
with the C++ compiler build.

In desperation I then tried to build newlib hoping that this will take care of the GCC build 
errors.  This is not working either.

The first command to build up to newlib works just fine up to the making of newlib.  The make fails 
after a LONG time with:

make[3]: Entering directory `/usr/local/src/build-tools/m68k-elf-newlib/m68k-elf/m68000/libgloss'
make[3]: *** No rule to make target `all'.  Stop.

make[1]: Leaving directory `/usr/local/src/uClinux/m68k-elf-newlib/m68k-elf/libgloss'
make: *** [all-target-libgloss] Error 2

Further back, there is a configure error which has to do with not being able to find 'crt0.o' 
during a configure compiler test... shouldn't this package be self contained??

Ok, so I created a crt0.o stub file that just defines the symbols with no code and now, after 
reinvoking configure and make,  it continues further until, after about an hour and half later:

gmake[4]: Entering directory `/usr/local/src/uClinux/m68k-elf-newlib/m68k-elf/m68000/mid-shared-library/libgloss/m68k'

What a nightmare.  Can anybody help?
