Thank you for the check-in.

The eCosCentric arm-eabi pre-built toolchains do not include StrongARM
multi-libs. AFAIK, users who want to build eCos for these targets will
therefore need to either build their own arm-eabi-gcc or revert to
CYGBLD_GLOBAL_COMMAND_PREFIX == "arm-elf" and use the older arm-elf-gcc
3.2.1. Can you please let me know what the intention is here so I can
mention this in the eCos 3.0 release notes?

This was discussed before IRL, and I believe until I hear to the contrary that strongarm should probably still work. It just won't be perfectly optimal as it will fall back to the arm7tdmi multilib (the default); but now actually looking at GCC sources, I think it may have only a virtually perceptible effect even then.


Actually there is one exception that should probably not be arm-eabi which is the AEB target, which is arm7di and so can't work with the new tools. Sorry I should have mentioned that yesterday Bart. Maybe it's worth putting that one back, but it may not be worth even that effort since no-one will be using it... I think it hasn't been sold for going on 10 years now.
