Sorry, I should have indicated which platform on my original email.

I'm compiling on cygwin. I'm targeting the syslinux installer for cygwin 
as well. Targeting the actual syslinux itself for x86 machines.

I know there is a mingw compiled syslinux, but people who spend most of 
their time in cygwin, it makes more sense to use a cygwin native 
syslinux installer than a mingw installer. Especially when you can use 
cygwin's /dev/sda notation as opposed to window's X: .

I've already built a cross compiler so that the gcc on cygwin can output 
ELF rather than PE32 for the syslinux itself. But I also still need PE32 
for the syslinux installer running on cygwin.

Could you also please tell me the process for compiling for win32/mingw? 
I'm assuming this is a 2-step process as mingw-gcc can't output ELF.
