'make manuals' is equivalent to 'make pdf' on Unix.

This could be overcome by using timestamps, as on Unix.  However, those do 
not work entirely right on Unix, as they only check if the package sources 
have been updated, and not that R has been changed in a way that needs the 
package to be regnerated (e.g. the C headers have changed, or methods need 
to be re-dumped).  So I have been reluctant to change to a known flawed 
system.  (Originally the Windows toolkit was missing 'touch', which you 
would need to do timestamps right.)
