Agner Fog released a very nice and usefull tool :

This utility can be used for converting object files between COFF/PE, OMF, ELF and Mach-O formats for all 32-bit and 64-bit x86 platforms. Can also be used as a cross-platform library manager, a dump utility, and a powerful disassembler. Source code included (GPL).

Interesting tool.

Imho, it's best to settle with an assembler that supports the output formats you need, but this tool could be handy for legacy code.

The author does not provide any change log. Probably, it's a maintenance release to fix some small bugs.
