Remove gxx.exe as well.  Then use gpp.exe (which comes with
gpp2952b.zip) instead.

Your gxx.exe is from the v2.8.1 distribution, so it looks for
cc1plus.exe in the lib/gcc-lib/djgpp/2.81, instead of in
lib/gcc-lib/djgpp/2.952.

The rule is: remove ALL the files that belong to the old version.
Section 4.7 of the DJGPP FAQ list shows one way of doing that
efficiently.

If the above still doesn't help, say "gpp -v t.cpp" and post here
everything that the compiler prints.  (You might look into that output
first, as it should give a clue as to what's happening.)

The 2.81 thing is hardwired into the compiler binary, because that's
how it was configured when it was built.  Since gxx.exe is from an old
distribution, it still wants to find its subprograms and libraries in
that place.  That's why it fails.
