I did what you say here, Ian, for the COFF object format, but am trying
to use ELF now and having the same problem. Obviously your
recommendation is COFF-specific. I have tried to build with ELF and have
verified that it is aligning sections on 4-byte boundaries (I need to
align on 2-byte boundaries). I grep'ed in the binutils-2.10/bfd
directory for "SECTION" and "ALIGNMENT" and saw nothing obvious that
applied to ELF.

Any ideas on how to do the same thing using ELF?

Thanks
