Visual Studio 6 was released in 1998. Though some people still use it because
of the MSCVRT.DLL issue, it's not easy to support and I don't currently have
access to it.
Lucy currently builds for me under Windows 7 with ActivePerl and the free
version of MSVC from 2010. If switching to a more recent version of MSVC
is an option for you, try that.

Charmonizer doesn't think this system provides large file support, because it
hasn't found a combination of commands that make the function S_probe_off64()
in charmonizer/src/Charmonizer/Probe/LargeFiles.c pass.
This combination generally works for MSVC:
{ "", "fopen", "_ftelli64", "_fseeki64", "__int64" },
However, some web research indicates that _ftelli64 and _fseeki64 were
introduced later and are not in VS6. For large file support under VS6, you
need to use _lseeki64, which operates on file descriptors rather than C89
FILE* streams.

This approach is actually feasible for Lucy, since we switched from FILE* to
file descriptors a long time ago. It will just take some rejiggering of
LargeFiles.c so that we don't depend on there being some form of fseek/ftell
when defining off64_t.
