Windows Build
-------------
Most of the notes in the README apply on Windows as well; however, to
configure and build follow the following steps:
o Make sure you have the required environment variables set for VC++. Often
this is accomplished by running the VCVARS32.BAT file from the VC++ bin
directory.
o Edit makefile.vc, updating the TIFF_DIR (or TIFF_LIB and TIFF_INC) variable
to point to the location of the tiff build tree.
o Build using the command ``nmake -f makefile.vc''
If you don't use makefile.vc, you will need to copy geo_config.h.vc to
geo_config.h by hand.
