Is there a way to use pre-compiled headers in VC++ without requiring stdafx.h?

Question

I\'ve got a bunch of legacy code that I need to write unit tests for. It uses pre-compiled headers everywhere so almost all .cpp files have a dependecy on stdafx.h which is

No. pre-compiled headers relies on a single header included by all sources compiled this way. you can specify for a single source (or all) not to use pre-compiled headers at all, but that's not what you want.

In the past, Borland C++ compiler did pre-compilation without a specific header. however, if two sources files included the same headers but at different order, they were compiled separately, since, indeed, the order of header files in C++ can matter...

Thus it means that the borland pre-compiled headers did save time only if you very rigidly included sources in the same order, or had a single include file included (first) by all other files... - sounds familiar ?!?!
