Current buildall.bat is just guick hack I did for easier and faster building.
Some improvements that would be nice:
- check if vcvars32.bat is run and warn user if not so
(check if environment variables are set?)
- add debug targets
- build shellextension (64-bit might be tricky)
More advanced thing would be to build a distribution:
- run setversions.bat from /src, version number as commandline param?
- build manual
- build installer?
