  The windows machine is not connected to the network (and may never be).
  config.log.tar.gz is attached.
  gcc is version gcc (tdm64-1) 4.6.1
  # sh
  # ./config.guess 
  # configfsf.guess
Your environment is broken.  A plain gcc invocation fails:

  configure:8657: gcc -o conftest.exe -m32 -O2 -pedantic -fomit-frame-pointer -march=pentiumpro   conftest.c
  ./configure: /c/MinGW64/bin/gcc: Invalid argument
I am sure you can reproduce this with manual commands.

You say this is a 64-bit system, but this seems to be a 32-bit system.
