[svn-r3966] Purpose:
    bug fix
Description:
    The last reported problem that the parallel example program
    in examples could not be compiled, could not be duplicated
    again.  I guessed maybe Rushad mistook the compile warning
    messages as error messages.  Just a guess.
    Furthermore, the changed examples/Makefile.in and configure.in,
    did not work for the parallel case.  The examples/ph5example.c
    was never included for compiling.
Solution:
    Removed the fix in configure.in, put ph5exmple directly back
    in the examples/Makefile.in but put it in a variable for
    easier future maintenance.  Also, easier to identify the
    parallel examples too.
Platforms tested:
    Eirene, both serial and parallel modes.
