I was mistaken in saying it comes with the Platform SDK; it's probably
with the .NET SDK. On my Windows 2000 system, the operating system is
installed on C:, while most development tools are on D:. Despite the
fact that I ordered all of these SDKs to install on D:, directories
"Microsoft Visual Studio .NET" and "Microsoft Visual Studio .NET 2003"
were still created in "C:\Program Files". The msvcrt.lib of which I
spoke is in "C:\Program Files\Microsoft Visual Studio .NET
2003\Vc7\lib", which I believe to be part of the .NET SDK. The .NET
SDK includes a non-optimizing version of VC++; msvcrt.lib accompanies
it, but seems to work fine with the optimizing VC++ included with the
"Toolkit 2003". I think this overlap was an unintentional slip on

No. To my knowledge, the official Microsoft C++ .lib file is not
available with any of the free SDKs. It can be generated from
msvcp71.dll, however (msvcp71.dll is included with both the .NET SDK
and the Toolkit 2003). I've found instructions on how to do this in at
least two places on the web. I'd link directly to them, but I'm not
sure how Microsoft's legions of lawyers feel about them, since it seems
that the omission of the dynamic runtime .lib files from the 2003
Toolkit was a deliberate bid to make it unsuitable as a replacement for
the full version of VStudio for most developers except students. If
you're Feeling Lucky, however, you might just strike it rich with
"missing the import library msvcprt.lib needed during linking".
