win64 question

[Satish Balay]

Win32fe [& cygwintools] are used only as part of the build
enviornment.  So 32bit version of these tools don't prevent 64bit
builds.

Internally win32fe will invoke 'cl' with correct options. Here 'cl'
will run in 64 bit mode - thus producing the correct 64bit object
files.

Note: you might have to follow the instructions in the "Using Visual
Studio 2005" section of the installation insctuctions. Make sure when
you use the 'VisualStudio CMD' - its the 64bit compiler version [and
then use win32fe --nodetect' options.
