Useful tip for MS Windows

what dies 'grep' do ?

grep can find all occurrences of a given pattern, but that really doesn't matter. The most important thing that you can unleash the power of Unix tools even on windows.

I tried cygwin and it failed building Qt4 on my old WinME (M$ Win paths and Unix paths mixed ...)

Just don't add path to Cygwin binaries to PATH environment variable. There's also MINGW_IN_SHELL.
