Because all the directories can be overridden on the configure
command-line, and there is no guaratnee that even the relative directory
structure will stay the same, I suggest that we pass the necessary
directories to pgadmin3 using CPPFLAGS and the -D directive. Something
like -DDATA_DIR would work. This would allow the use of the DATA_DIR
preproccessor definition within the C++ code.
