This was fixed in the Boost version of regression.py using:
   shutils.rmtree( unicode( path ))

(see my updated regression.py that fixes this issue and an issue when 
running monitored builds).

At the moment, regression.py is using cmd.exe and del to perform the 
regression tests when I use a Windows version of Python, even though I have 
cygwin installed. Since I have cygwin installed, I would like to use rm, 
tee, etc. even if I am running the Windows version of Python.

This can be fixed by using this function:

def platform_id():
    if sys.platform == 'win32':
        # Try to use the tee command (part of cygwin and mingw 
distributions)
        text = 'Is this really cygwin?'
        file = 'cygwin-test.tst'
        os.system( 'echo %s 2>&1 | tee %s 2>&1 >nul' % ( text, file ))

        # If the test file exists, then we have tee...
        if os.path.exists( file ):
            line = open( file ).readline().replace( '  \r\n', '' )
            os.unlink( file )

            # If the file contains the text we outputted, assume the cygwin
            # tools are available...
            if line == text:
                return 'cygtools'

    return sys.platform

Also, my cygwin version of python chokes on the call to platform.system():

Traceback (most recent call last):
  File "./regression.py", line 918, in ?
    commands[ command ]( **accept_args( args ) )
  File "./regression.py", line 804, in accept_args
    options = {
  File "./regression.py", line 107, in platform_name
    return platform.system()
AttributeError: 'module' object has no attribute 'system'

The fix is to have:

def platform_name():
    if sys.platform == 'win32':
        return 'Windows'
    elif sys.platform == 'cygwin':
        return 'Windows/Cygwin'

    return platform.system()
