Well, in case if it's only possible to convert ELF executable how is that could be useful in my case?.. 
I want to test codec performance and for that I need to make millions of function calls in a loop to measure performance. In the ELF binary obviously I can't use anything that's os specific (file access for example). Or can I if I link to dynamic libc? The only possibility in this case is to embedde binary data into executable and process it by the executable. In this case I can't verify the output (unless I embed expected output also)
Maybe there are some other alternatives? Or maybe I could write a tool myself that dumps symbols into symbolsrec and then properly creates windll? I could build my code by VS and then simply replace chunks of machine code in that dll
