The pg_config_paths.h file was added by me to give files access to
configure paths, in part to allow relocation of install files.

Looking at LOCALEDIR in the two include files, I realize one uses prefix
while another optionally uses $ac_default_prefix, but if LOCALEDIR were
different in the two cases, "NONE" would be prepended to one of them.

I have attached a patch that removes the LOCALEDIR from pg_config.h, and
changed fe-misc.c to make use of the pg_config_paths.h define. I think
this is appropriate only for CVS HEAD.

We have not seen warnings about the two defines only because they are
always define the same.
