[ scratches head... ]  Weird.  Evidently something is going wrong with
the quoting of those make variables; but the gcc command line looks
exactly as it should, AFAICT.  Are you using a nonstandard shell, or
something other than the stock gcc installation?

A slightly far-fetched possibility is that you have a corrupted ccache
entry for this file.  In a standard RHEL6 installation, "gcc" really
invokes "ccache gcc", so the lack of any mention of ccache in the given
command line doesn't eliminate this theory.  If you can't find any other
explanation, you might try "rm -rf ~/.ccache" and see if that makes it
better.

(FWIW, PG9.2 builds fine on RHEL6.8 for me, and I'm sure it built fine
on 6.4, back when I was running that.)

Hm, ccache RPM not installed then?

Don't know what to tell you.  RHEL 6.4 was current during 2013, which is
the same year that 9.2 was our current release, and we would certainly
have noticed if there was any widespread (or even not so widespread)
build failure on that combination.  Also, the code in question hasn't
changed in quite some time, so the issue would affect other PG branches
besides 9.2, making it even less likely that we'd have missed a problem.
I have to think that one or another component of your toolchain is
nonstandard or corrupted, but it's hard to say more than that.

Well, Postgres isn't going to care.  Applications that make use of the
output of pg_config might be unhappy with the lack of quotes, although
most likely it wouldn't matter as long as there's not spaces or quotes
in your path names.
