cygwin arm-elf-linux gcc build failure

[John Andrews <john at triscend dot com>]

Hi All,

I've made it past a number of cross gcc build errors based on the sage
advice (both to myself and others) from the ubergeeks of this list. Many
Thanks!

But now I'm stumped again. After rereading all of the archives, FAQs and
assorted web pages I can't get a clue regarding this one.

Binutils built and installed without incident using the default destination.

The gcc build is now making it to libgcc2 and barfs on something in
gthr-posix.h. I've tried running dos2unix CRLF -> CR converter on just this
file, and also on all of the headers. The converted file sizes are the same
as the preconverted and it doesn't change the error.

In addition to installing binutils I've:

# change Hint to ARM_Hint in /usr/src/gcc-2.95.2/gcc/config/arm/arm.h and .c
gvim&
# make linux and asm links in /usr/local/arm-elf-linux/include, 
# usr/local/include doesn't seem to be searched by xgcc for libgcc1
# missing asm/unistd.h
cd /usr/local/arm-elf-linux
mkdir include
cd include
ln -s /usr/src/uClinux-2.4.x/include/linux
ln -s /usr/src/uClinux-2.4.x/include/asm-armnommu asm
# I guess we're going with newlib for now
# copy headers to include missing stdlib.h and unistd.h for libgcc2
cp -r /usr/src/newlib-1.9.0/newlib/libc/include/*
/usr/local/arm-elf-linux/include
#configure gcc
cd /usr/src/build-2.4.x/gcc
../../gcc-2.95.2/configure --target=arm-elf-linux \
      --enable-languages=c \
      -v 2>&1 | tee configure.out
# make
make LANGUAGES=c | tee make.out

Then it chokes with the output listed below. I did notice that the binutils
configure named the host as i686-pc-cygwin, while the gcc configure called
it i686-pc-cygwin32. I don't know if this makes a difference or not.

Many Many Thanks for your irreplaceable help...
