# Because this test sets SConsignFile(None), we execute our fake
# scripts directly, not by feeding them to the Python executable.
# That is, we chmod 0755 and us a "#!/usr/bin/env python" first
# line for POSIX systems, and add .PY to the %PATHEXT% variable on
# Windows.  If we didn't do this, then running this script with
# suitable prileveges would create a .sconsign file in the directory
# where the Python executable lives.  This can happen out of the
# box on Mac OS X, with the result that the .sconsign statefulness
# can mess up other tests.
