I tried just copying stuff around, but something in the script
overwrites anyhow.

m4.exe exists in the VS path and the MingW path. It is the
current build from the GnuWin32 project.
G:\vs-build>.\bin\m4.exe --version
GNU m4 1.4.2
G:\vs-build>%COMSPEC%
Microsoft Windows XP [Version 5.1.2600]

I did try copying them, and as you can see from my first post,
the timestamp on the file is apparently irrelevant. It will get
overwritten by either the script or the .DSP project.
With the exception of the .cpp in the src/modules folder, which
is left alone.

Something changed in the way the batch files are parsed I
suspect. MS has done this before between NT4 and 2K.

Hard work spotlights the character of people; some turn up
their sleeves, some turn up their noses, and some don't turn up
at all!
