Fix DVI/PDF manual build

[Joseph S. Myers]

May I remind people that changes to the Texinfo manuals should be tested 
with "make dvi" or "make pdf", as described in contribute.html.  I've 
applied this patch to fix these; the nightly update of online 
documentation was failing to build the gfortran PDF manual for the past 
few days, <http://gcc.gnu.org/ml/gccadmin/2007-q3/msg00132.html> onwards.
