building for cygwin (nearly there)

["Bruce Adams" <bruadams at tycoint dot com>]

Hi,
    I am (still!) trying to build a m68k-elf compiler for windows 2000 under
cygwin.  I have compiled
and installed binutils with make check reporting only one failure
"ld-discard/extern".  
The path seems to be what was causing some of my problems.  Putting my
prefix path
before cygwin seems to fix some of the issues.  I would definitely recommend
putting that one in the FAQ in big friendly letters.  It stumped me for
ages.  
Still I can't help thinking that if the order of the path is important then 
there is something wrong with the system.  Surely we would all be better off
if when the cross
compiler wants to use the cross compiler it use e.g. m68k-elf-gcc instead of
just gcc.  Plain 'ol gcc by itself is just asking for trouble.  Not to
mention
the fact that I'd rather typing gcc myself invoked the native compiler
rather
than a half constructed cross compiler (this is in the case that --prefix is
not
the same location as the normal gcc).

I can compile and install the partial gcc using the following:

PREFIX=/cygdrive/c/gccm68k
TARGET=m68k-elf
HOST=i686-pc-cygwin
GCCDISTO=gcc-3.2-core

make distclean
../${GCCDISTO}/configure --target=$TARGET --prefix=$PREFIX --build=$HOST
--host=$HOST \
 --enable-languages=c --with-gnu-ld --with-gnu-as --without-headers
--with-newlib --verbose \
 2>&1 | tee configure.log

make ac_cv_prog_cc_cross=yes cross_compiling=yes

Where gcc-3.2-core does NOT include the newlib sources.

I cannot compile in a single operation (using the same configure command
with or without c++ added) when the newlib directory is added to the gcc
source 
tree.  Oddly it fails compiling libiberty (regex.c) rather than compiling
newlib (complaining that the size of a buffer structure is unknown).  It
looks like it never got as far as compiling newlib.

Anyhow I can at last build and install newlib-1.10.0.
But the second stage compilation fails on libstdc++.  

Making all in libsupc++

Anyone know how to fix this?
