MSVC 6.0 does not have odbc.h (just checked that).

The problem is that Windows-native C/C++ compilers have no configure
tool, so I think that by default all non-ISO features should be
disabled, and there should be an instruction how to modify makefile
and config.h to enable such additional features. This concerns ODBC as
well as GMP and zlib.
