If you build a static ELF executable in `ld -q` mode (which leaves rela sections inside the binary) then you can run it through the elf2pe.com program afterwards, which will turn it into a PE executable. We have a new trick for defining WIN32 DLL imports in C without any assembly code. This also achieves the optimally tiny and perfect PE binary structure. We need this because it isn't possible to have a GNU ld linker script generate a PE file where the virtual pointer and the file pointer can drift apart. This post-linker can do that. One cool benefit is we can now use a smaller 512-byte alignment in the file, and an even bigger 64kb alignment for the segment virtual addresses, and the executable ends up being smaller. Another program introduced by this change is pecheck.com which can do extensive linting of PE static executables to help explain why Windows won't load it.
