[ECOS] Int Vectors and Build Problem

[Leo McManus <leomcmanusir at yahoo dot com>]

ARM720T on ARM Integrator board.

After building my eCos executable, I can see in my Srecord and with my GDB,
that the int vectors, which are loaded at download time to address 0x40000 and
later copied to address 0x0, point to address 0xE59FF018, which holds no
memory. This is worked out at compilation time.

Would anyone know where these values maybe picked up from? Am I missing
anything in my linker file below?

Thanks

Leo
