Window build broken

[lonetiger at gmail.com]

Well the error is correct, it’s just checking against the machine type in the PE spec:

IMAGE_FILE_MACHINE_AMD64
0x8664
x64
So somewhere along the line an invalid PE file was generated (or for the wrong architecture).

Wow, I happened to try building GHC on Windows for the first time ever
today, and I also experienced this error :)

Interestingly, someone reported a very similar error to this on Trac,
but for GHC 7.8.3 [1]. Here's where the error message comes from [2]
in Linker.c:

    static int verifyCOFFHeader
    (COFF_header *hdr, pathchar *fileName)
    {
      if (hdr->Machine != 0x8664) {
        errorBelch("%" PATH_FMT ": Not x86_64 PEi386", fileName);
        return 0;
      }
      ...
    }
