Which I think in the "-v" it's the "(cygming special)".

Thanks :-)

OK. Volodya mentioned that the bug is likely not in the toolset code I 
change but in one of the regex functions :-(

No way other than testing ourselves on as many platforms as possible. 
But it's hard to do this as we don't personally have access to that many 
setups. And especially because some problems only show up after trying 
to use the tools, rather than when running the regression tests BBv2 
has. Now if we had a way of checking in changes and having others test 
them without inflicting on everyone that would likely be ideal. Only way 
I can think of doing that without too much pain is to have the 
regression testers (i.e. regression.py) do an initial BBv2 test with the 
  new code. But for doing the rest of the testing have it use a known to 
work tagged version. That is use something like a BUILD_TESTED CVS tag.
