Log:
[NTVDM]: Use variable-length buffers in DisplayMessage, in case we display a
very long message (uses the _vscwprintf CRT function, not available on Win2k.
You need to recompile NTVDM with WIN2K_COMPLIANT define if you want to be able
to run it on win2k. In that case DisplayMessage uses a quite large enough
buffer for its needs). If somebody knows an alternative to _vscwprintf that
does the very same job, and which exists on Win2k, I would be happy to use it
instead.
Since _vscwprintf will do the whole work already anyway, you could as
well directly print it into the static buffer. You could use _vsnwprintf
or StringCbPrintfW, which internally uses the former, and use the result
to decide whether the buffer was large enough. This will be more
performant, since you only need to print once, when the buffer is large
enough.
