  Log:
    win32/setup.mak: get target architecture from the compiler
    
    * win32/Makefile.sub, win32/setup.mak (MACHINE): get target
      architecture from the compiler, instead of environment variable
      at build time, which is irrelevant to runtime environment, and
      not set when running in cygwin sshd.

    trunk/win32/Makefile.sub
