You have run into a limitation of the COFF file format. With COFF all(*)
sections have a 4 byte alignment, so the output section is padded to a 4 byte
boundary.
There are two possible solutions to your problem:
1. Switch to a better file format. (Go on, do it. You know that ELF makes
sense... :-)
2. Hack the assembler and linker so that the default section alignment is
two bytes instead of four. The attached patch will do this. You will have to
build and install the assembler and linker of course.
Cheers
Nick
(*) There are a few exceptions, but they have fixed names. You cannot just
choose the alignment for an arbitrary section.
