I have just committed plc++demos.h and done all the necessary Makefile.am
and c++ examples changes to use it.  Also, I have made appropriate changes
to the c examples so that M_PI is now #defined and used consistently for
all the c and c++ examples.

I see no build problems with make check in the build tree or make in the
installed examples tree.  Also, the c++ and c postscript results look good
and agree exactly (except for date).
