How to convert PE(Portable Executable) format to ELF in linux

Question

Hi

What's the best tool for converting PE binaries to ELF binaries?

Following is a brief motivation for this question:

1. Suppose I have a simple C program.
2. I compiled it using gcc for linux(this gives ELF), and using 'i586-mingw32msvc-gcc' for Windows(this gives a PE binary).
3. I want to analyze these two binaries for similarities, using Bitblaze's static analysis tool - vine(http://bitblaze.cs.berkeley.edu/vine.html)
4. Now vine doesn't have a good support for PE binaries, so I wanted to convert PE->ELF, and then carry on with my comparison/analysis.

Since all the analysis has to run on Linux, I would prefer a utility/tool that runs on Linux.

Thanks
