Only if my assumption is correct that the PROTOTYPES really are
sufficient for <gb_graph.h> to be #included safely in
<stanford_graph.hpp> in an "extern "C"" group. Moreover, not every
user of SGB is aware of the possibility to "ln -s PROTOTYPES/* ."
before running "make tests" and "make install" (nor is he/she
necessarily in a position to run these steps himself/herself).

Unfortunately, all I have here is a Pentium-I PC at 133 MHz and 32 MB
of RAM, and it takes _a_long_time_ to compile the "graph" stuff, so I
am not (yet) in a position to test a modified <stanford_graph.hpp>.
If possible, I'll report on this tomorrow, when I have access to a
P-II at 350 MHz with sufficent RAM.

However, I could imagine that a patched <gb_graph.h> headerfile could
well be used in <stanford_graph.hpp>, thus eliminating the SGB stuff
for "updated" setups of SGB.

Today I submitted a report to Don Knuth regarding the Boost Graph
Library and the compatibility issue raised by <gb_graph.h>. However,
I doubt that DEK would apply extensive changes to sGB per se.
