I'm assuming that the format you mention here is the same as the OMF
format used by Borland tools. GNU tools do not support OMF format, and 
until Borland changes it format to the more common and widely used 
PE-COFF, it shall remain that way (unless someone contributes the code 
needed to support OMF format of course). Even with PE-COFF, current 
binutils is not in general link compatible with MSVC compiled .OBJ 
files, but that'll hopefully change in the future.

Please see my dllhelpers package for g77 DLL example.
