# there are some tests that have pre-built shared libraries, and these
# windows dll files must have execute permission. Adding execute
# permission may happen automatically on windows when using certain
# versions of mercurial but it cannot be guaranteed. And blindly
# adding execute permission might be seen as a mercurial 'change', so
# we avoid adding execute permission to repository files. But testing
# from a plain source tree needs the chmod a+rx. Applying the chmod to
# all shared libraries not just dll files. And with CYGWIN and sshd
# service, you may need CYGWIN=ntsec for this to work.
