As I understand it, the -fleading-underscore flag is only useful to add
a leading underscore for targets that do not have a leading underscore,
like linux.  It won't accomplish anything on one that already has it,
like PE.

There is absolutely no way that you can use an object compiled for Linux
with Cygwin.  The fact that symbols don't have a leading underscore is
trivial compared to the massive differences between ELF and PE formats. 
There is just no chance of this working even if you solved the
underscore issue.
