I wrote a new version of the patch
that tries to implement most of the things we talked about.

  It works quite nicely on my windows 7 64-bit using
cygwin, mingw32 or a cross-built mingw64 binary.

  Interestingly, it seems that the mingw64 binary is
not really affected by this issue because the 64-bit system DLLs
do have a section offset of 0x1000 for .text section,
while the 32-bit DLLs have 0x10000.
