Subject[PATCH v3] Make elf2ecoff work on 64bit host machines
Date
Use fixed width integer types for ecoff structs to make elf2ecoff work
on 64bit host machines

Signed-off-by: Thomas Bogendoerfer <tbogendoerfer@suse.de>
Reviewed-by: Paul Burton <paul.burton@mips.com>
---

v3: include stdint.h in ecoff.h
missed one printf format

v2: include stdint.h and use inttypes.h for printf formats
