[ECOS] Arm Thumb gcc tools Cygwin installation help required

  I just finished building the Arm Thumb tools for the
same board.  The version were:

A couple of notes though.

gcc-3.x for a different processor won't build with less than
gcc-3.x as the native compiler.  You will need to upgrade to
gcc-3.x.  '/<src_dir>/configure bootstrap' is the magic phrase.
Please check the appropriate docs for more detailed info.  I'm
typing from memory and I have slept since then.

I'm not sure newlib is required for eCos, I built it anyway.

NEITHER of the patches listed on the eCos page for building
the Arm tools is required.

gcc-3.0.4 did not build libstdc++.a  I have no idea why.
When you build the libraries for eCos the 'target.ld' file
lists it in the list of libraries.  After reading several posts
about it in the archives, I removed it from 'target.ld'  The test
and example programs still link without complaints.

Warning - I'm new to eCos and haven't built gnu tools for some time.
If anyone can add more info or correct any mistakes I've made, it
won't hurt my feelings.
