Patch works as intended - in case you hadn't tested it on win32. I
assume using "%j" will always return "001" and never "1"? My man page
says it does, but I'm not sure if it's portable everywhere.

Yes! This is very important!

Yes, we no longer support building from cvs on vc/bcc unless you do the
"distprep" step manually using mingw (or unix) first.

Yes, please!

Thanks a lot for fixing this.
Question: Would it be trivial to add the same thing to the rest of the
DLLs/EXEs? (No need in distprep, just in the general rule). Check
Makefile.global.in around line 405. Since we already have build rules
that 'sed' on the rc file...
If it's a lot of work, leave it for later. But if it's not too much, it
would be quite helpful on these DLLs/EXEs as well.
