Mailman uses vsnprintf in it's C wrapper.  There's a simple configure
test...

# Checks for library functions.
AC_CHECK_FUNCS(vsnprintf)

...and for systems that don't have a vsnprintf, I modified a version
from GNU screen.  It may not have gone through the scrutiny of
Apache's implementation, but for Mailman it was more important that it
be GPL'd (not a Python requirement).
