No, it isn't. This emerges as a Python 2.4 FAQ.

Yes, it is.

Why do you say that? PCbuild/readme.txt starts with

Building Python using VC++ 7.1
-------------------------------------
This directory is used to build Python for Win32 platforms, e.g. Windows
95, 98 and NT.  It requires Microsoft Visual C++ 7.1
(a.k.a. Visual Studio .NET 2003).
(For other Windows platforms and compilers, see ../PC/readme.txt.)
