make dist failure

[Lars H. <lhe...@us...>]

$ make dist
...
make[1]: Entering directory `/home/user/src/cvs/gnuplot/docs'
make[1]: *** No rule to make target `pdffigures.tex', needed by `distdir'.  Stop.
make[1]: Leaving directory `/home/user/src/cvs/gnuplot/docs'
$ 

 make dist must be standalone, i.e. be able to run straight after configure
 without having to build anything first. Also, the pdffigures target needs
 some work; going by the error message above, I should be able to
  cd docs; make pdffigures.tex
 but there's no such target.
