Problem: - cpu amd64 was not recognized
- failed to link with static system library
Fix: add amd64, remove unnecessary library
I have no ia64 test machine, but it should run there as well.
Fix: This patch introduces three extra files/patch* files.
cnf/mak/aleph-gcc-3.mak is changed to remove unused libsupc++
The others add definitions to recognize amd64 (no special handling required)
